Zhang, Wei;Yan, Liangguo;Wang, Qiaodi;Li, Xuguang;Guo, Yanxiu;Song, Wen;Li, Yanfei research published 《 Ball milling boosted the activation of peroxymonosulfate by biochar for tetracycline removal》, the research content is summarized as follows. Biochar materials have been commonly applied in advanced oxidation processes, and various strategies were explored to enhance the practical performance of biochar. In this study, ball milling, a simple grinding method, were used to treat biochar, and the ball-milled biochar materials were used to activate peroxymonosulfate (PMS) for tetracycline (TC) removal. It was demonstrated that the ball-milled biochar materials using different ball mass ratios and ball milling time benefited the generation of oxygen-functional groups and defects on the surface, thereby enhanced the catalytic performance of biochar to degrade TC. Besides, the different exptl. conditions (initial pH, catalyst dosage, PMS dosage, and TC dosage) and coexisting substances all affected the degradation efficiency of TC. ESR and radicals quenching experiments showed that the radicals attached to the biochar contributed greatly to the degradation of TC, and both free radicals and non-free radicals participated in the TC degradation process.
2403-88-5, 2,2,6,6-Tetramethyl-4-piperidinol(TEMPO) is a useful research compound. Its molecular formula is C9H19NO and its molecular weight is 157.25 g/mol. The purity is usually 95%.
TEMPO is an intermediate used in the preparation of Piperidinyloxy free radical derivatives.
TEMPO is an organic compound that acts as a radical scavenger. It is stable in the presence of water and air and can be used for the inhibition of bacterial growth. TEMPO reacts with reactive intermediates to form non-reactive substances and terminate chain reactions. This process is optimal at temperatures between 0°C and 40°C and pH values between 3.5 and 7.5. TEMPO has been shown to inhibit the growth of bacteria by reacting with reactive molecules such as amines, chlorides, or low energy radicals in aqueous solution. TEMPO also has genotoxic activity that inhibits DNA synthesis in bacterial cells through oxidation of guanine residues on DNA molecules., Synthetic Route of 2403-88-5
