And the article contained the following:

In this study, physio-chem. properties, 45 antibiotics, 6 heavy metals, 42 antibiotic resistance genes (ARGs), 3 mobile genetic elements, and the bacterial community structure were investigated to analyze the fate of ARGs during sheep manure aerobic heap composting. Results showed that sheep manure heap composting could produce mature compost. The degradation processes reduced the total antibiotics content by 85%. The abundance of ARGs and mobile genetic elements (MGEs) were enriched 9-fold, with the major increases to sul and tet genes (sulI, sulII, tetQ, and tetX). Tetracycline and sulfonamide resistance genes were the most abundant ARGs after composting (more than 88% of all genes). The genes tetA, tetX and sulI were related to the most diverse bacteria that were most able to proliferate during heap composting. Therefore, sulI and tetX are the major ARGs to be controlled, and Actinobacteria and Bacteroidetes may be the major host bacteria. The experimental process involved the reaction of N-((4-Aminophenyl)sulfonyl)acetamide(cas: 144-80-9).Recommanded Product: 144-80-9

On May 31, 2021, Camargo-Perea, Ana L.; Serna-Galvis, Efraim A.; Lee, Judy; Torres-Palma, Ricardo A. published an article.Application In Synthesis of N-((4-Aminophenyl)sulfonyl)acetamide The title of the article was Understanding the effects of mineral water matrix on degradation of several pharmaceuticals by ultrasound: Influence of chemical structure and concentration of the pollutants. And the article contained the following:

Degradation of seven relevant pharmaceuticals with different chem. structures and properties: acetaminophen (ACE), cloxacillin (CXL), diclofenac (DCF), naproxen (NPX), piroxicam (PXC), sulfacetamide (SAM) and cefadroxil (CDX), in distilled water and mineral water by ultrasound was studied herein. Firstly, proper conditions of frequency and acoustic power were determined based on the degradation ability of the system and the accumulation of sonogenerated hydrogen peroxide (24.4 W and 375 kHz were found as the suitable conditions for the sonochem. treatment of the pharmaceuticals). Under such conditions, the pharmaceuticals degradation order in distilled water was: PXC > DCF ∼ NPX > CXL > ACE > SAM > CDX. In fact, the initial degradation rate showed a good correlation with the Log P parameter, most hydrophobic compounds were eliminated faster than the hydrophilic ones. Interestingly, in mineral water, the degradation of those hydrophilic compounds (i.e., ACE, SAM and CDX) was accelerated, which was attributed to the presence of bicarbonate ions. Afterwards, mineral water containing six different initial concentrations (i.e., 0.331, 0.662, 3.31, 16.55, 33.1, and 331μM) of selected pharmaceuticals was sonicated, the lowest concentration (0.331μM) always gave the highest degradation of the pollutants. This result highlights the great ability of the sonochem. process to treat bicarbonate-rich waters containing pollutants at trace levels, as pharmaceuticals. Finally, the addition of ferrous ions to the sonochem. system to generate a sono-Fenton process resulted in an acceleration of degradation in distilled water but not in mineral water. This was attributed to the scavenging of sonogenerated HO• by bicarbonate anion, which decreases H2O2 accumulation, thus limiting the Fenton reaction. The experimental process involved the reaction of N-((4-Aminophenyl)sulfonyl)acetamide(cas: 144-80-9).Application In Synthesis of N-((4-Aminophenyl)sulfonyl)acetamide

On May 31, 2022, Zhi, Suli; Zhou, Jing; Zhang, Zulin; Zhang, Keqiang published an article.Quality Control of N-((4-Aminophenyl)sulfonyl)acetamide The title of the article was Determination of 38 antibiotics in raw and treated wastewater from swine farms using liquid chromatography-mass spectrometry. And the article contained the following:

The present study firstly aimed at developing a multi-residue method to identify and quantify 38 veterinary antibiotics (belonging to five different classes) not only for raw swine wastewater but also for wastewater differently treated by different units. The proposed method is based on a solid-phase extraction procedure and ultra high performance liquid chromatog. with mass spectrometry. For sample preparation, the optimal loading sample volume was selected as 50 mL, the pH of which was adjusted to approx. 3.0 using formic acid. Then 0.1 g/L EDTA disodium salt was added. The recovery rates for different types of wastewaters were in the range of 35.94-124.51% and the relative standard deviations were in the range of 0.36-14.62%. All the matrix standard curves exhibited high linearity (0.9956-0.9999). The matrix effects for the target antibiotics ranged from -61.73 to +148.75%. To ensure the practicality of the method, we performed the detection of the actually added concentration to determine method detection limits and quantitation limits. The quantitation limits of most of the target antibiotics were 0.04μg/L, except for spiramycin (0.1μg/L) and roxithromycin (0.2μg/L). This optimized and validated method was applied to analyze antibiotic residues in swine water samples from four swine farms. The experimental process involved the reaction of N-((4-Aminophenyl)sulfonyl)acetamide(cas: 144-80-9).Quality Control of N-((4-Aminophenyl)sulfonyl)acetamide

Wu, Chenggui; Cheng, Hong-Gang; Chen, Ruiming; Chen, Han; Liu, Ze-Shui; Zhang, Jingyang; Zhang, Yuming; Zhu, Yuxin; Geng, Zhi; Zhou, Qianghui published an article in 2018, the title of the article was Convergent syntheses of 2,3-dihydrobenzofurans via a Catellani strategy.COA of Formula: C11H9NO3 And the article contains the following content:

A cooperative catalytic system comprising a Pd/XPhos complex and a potassium salt of 5-norbornene-2-carboxylic acid to promote the annulation between aryl iodides and epoxides was developed, thereby providing highly convergent access to valuable 2,3-dihydrobenzofuran (DHBF) scaffolds. The unique potassium salt of the inexpensive 5-norbornene-2-carboxylic acid serves as a highly efficient catalytic mediator (10 mol%), which leads to fewer side reactions. The salient features of the reaction include its broad substrate scope (with respect to both aryl iodides and epoxides), its high atom economy and good chemo-selectivity. Furthermore, no extra base is needed for the process. The experimental process involved the reaction of 2-(Oxiran-2-ylmethyl)isoindoline-1,3-dione(cas: 5455-98-1).COA of Formula: C11H9NO3

On July 8, 2022, Yang, Lei; Wu, Xiaona; Chen, Xiaoyu; Chen, Fei; Zheng, Xiaona; Song, Qinan; Liu, Xiang; Li, Miao published an article.COA of Formula: C8H10N2O3S The title of the article was Synergistic Removal of Nutrient Pollutants and Pharmaceutical and Personal Care Products (PPCPs) from Contaminated Groundwater: Macro- and Microelements and Microorganisms. And the article contained the following:

The synergistic removal performance of nutrient pollutants and pharmaceutical and personal care products (PPCPs) from contaminated groundwater, and the biogeochem. interactions of macro- and microelements-contaminants-microorganisms were further studied. The electrolysis-zeolite/basalt system proved to achieve better synergistic removal performance than all other purification systems considered, reaching average removal efficiencies of 85.8% for nutrient pollutants and 74.7% for PPCPs. Electrolysis not only enhanced the abundance and distribution of MOB and DNB, but also promoted the production of microelements Fe3+ (0.1 ± 0.1 mg/L) and Zn2+ (0.3 ± 0.3 mg/L). Macroelements Ca2+ and Mg2+ increased by 27.8 ± 2.7 and 16.5 ± 9.6 mg/L, resp., which significantly stimulated the activities of function microbials. Microelements Fe3+ exchanged from zeolite, Mn2+ from basalt, and Cu2+ from groundwater itself were crucial for enzyme activity. Meanwhile, Mn2+ was co-regulated by oxidation-reduction processes and ion-exchange strength. Thus, the electrolysis-zeolite/basalt system is a promising technol. for synergistic nutrient pollutant and PPCP removal from contaminated groundwater, especially in dispersive water supplied in the countryside of China. The experimental process involved the reaction of N-((4-Aminophenyl)sulfonyl)acetamide(cas: 144-80-9).COA of Formula: C8H10N2O3S

On March 15, 2022, Li, Xitong; Liang, Kaiming; Yang, Bo; Xiao, Ke; Duan, Huabo; Song, Guangqing; Zhao, Huazhang published an article.Formula: C8H10N2O3S The title of the article was Preparation and application of a targeted magnetically separated catalyst for sulfonamides degradation based on molecular dynamics selection and mechanism analysis. And the article contained the following:

As refractory pollutants, sulfonamides (SAs) are widely distributed in the aquatic environment. The existing methods for advanced oxidation used to remove SAs from water received wide attention. In this study, surface mol. imprinting technol. has been used to prepare targeted catalysts that can be rapidly separated The results showed that molecularly imprinted catalysts can significantly improve the removal capacity of sulfonamides. When compared to Fe3O4, the removal rates observed for 3 different SAs increased by 98, 20 and 61%, resp. over 480 min on target catalyst and a good magnetic separation effect was observed in short time. The theor. results show that the optimal imprinted conditions can be quickly determined by analyzing the energy variation in the optimized system. Combined with energy anal. and free radical detection, the effects of weak interactions such as hydrogen bonds and van der Waals forces on the selective recognition ability of the materials were determined The results also show that the selective recognition process mainly exists in the higher activity groups (-NH2 and -NH-) that connect to the benzene ring in SAs. The catalysts also maintain their targeted catalytic activity in complex water samples. The results show that computational chem. and mol. imprinting can be used to design and prepare a targeted catalyst quickly and analyze the mechanism of its targeted degradation process. This study can provide reference for the rapid design of targeted catalysts and an improvement in the degradation efficiency of refractory pollutants found in wastewater. The experimental process involved the reaction of N-((4-Aminophenyl)sulfonyl)acetamide(cas: 144-80-9).Formula: C8H10N2O3S
