This work presents a novel CuS/percarbonate/tetraacetylethylenediamine (CuS/SPC/TAED) process for the degradation of sulfamethazine (SMT). Results indicated that the CuS/SPC/TAED process enabled the efficient generation of peracetic acid (PAA), which can be efficiently activated by CuS in alk. reaction media, and 93.6% of SMT was degraded in 30 min. Mechanism study revealed that the available reactive oxygen species (ROS) including hydroxyl radical (•OH), carbonate radical (CO•-3), superoxide radical (O•-2), singlet oxygen (1O2), and organic radicals (R-O•). Among them, R-O• (acetyloxyl radical (CH3CO•2) and acetylperoxyl radical (CH3CO•3)) were confirmed to be the primary species that contributed to SMT degradation Simultaneously, the role of sulfur species and carbonate ions were explored. It was found that the reductive O•-2 and sulfur species rendered the efficient redox of Cu species. Besides, the effects of key influencing factors including SPC/TAED mole ratio, CuS dosage, initial pH, temperature, and nontarget matrix constituents on SMT degradation were examined Finally, the degradation intermediates of SMT was identified, and the toxicity of these products was estimated by quant. structure-activity relationship (QSAR) anal. Overall, this work offers a new and simple strategy for antibiotic-polluted water remediation. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Synthetic Route of C10H16N2O4).
N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4) belongs to amides. The solubilities of amides and esters are roughly comparable. Typically amides are less soluble than comparable amines and carboxylic acids since these compounds can both donate and accept hydrogen bonds. Tertiary amides, with the important exception of N,N-dimethylformamide, exhibit low solubility in water. In simple aromatic amides, fragmentation occurs on both sides of the carbonyl group. If a hydrogen is available in N-substituted aromatic amides, it tends to migrate and form an aromatic amine and the loss of a ketene.Synthetic Route of C10H16N2O4
