A thorough discussion was conducted to explicate the peroxydisulfate activation and catalytic ozonation mechanism via radical quenching experiments, oxygen functional group, and electrochemical analysis. Bisphenol A elimination was determined by the combined effects of free-radical dominated pathway and ...

To gain insights into the mechanistic details of this transformation, radical trapping experiments were carried out (Scheme 2). When different amounts of 2,2,6,6-tetra-methylpiperidine-1-oxyl (TEMPO) were added into the reaction of 1a and 2a under the standard reaction conditions, the yield ...
In both assays, carvedilol displayed negligible antioxidant activity, while the three metabolites all proved superior radical inhibitors to BHT, with radical-quenching abilities in the order 3-hydroxy- > 5′-hydroxy > 4′-hydroxycarvedilol. Among the metabolites, 3-hydroxycarvedilol displayed even ...
图4 铁改性蒙脱土活化过硫酸盐降解双酚A体系中自由基的淬灭实验 Fig. 4 Radical quenching experiments of BPA system through PMS activation by Fe-MMT 当向反应体系中投加10 mmol/L叔丁醇(TBA)时,双酚A的去除率由96.4%降至75.9%。相较于甲醇的淬灭作用而言,叔丁醇对Fe-MMT/PMS/BPA反应体系的抑制作用明显减弱...
The combination of catalyzing carbonization and free‐radical quenching mechanism is proposed to be a promising strategy for the preparation of high‐efficiency flame‐retardant polypropylene (PP). Herein, a novel functionalized zirconium phosphate (RQZrP) nanosheet with free‐radical quenching capability ...
