Fig. 1a shows the curves of atrazine degradation with PS in the absence or presence of AA. In the absence of AA, about 14% of atrazine was degraded in the aerobic (PS/Air) or anaerobic (PS/Ar) condition within 6 h. As expected, the degradation percentage of atrazine in the presence of AA in the aerobic (AA/PS/Air) or anaerobic (AA/PS/Ar) condition reached 66% and 100%, respectively, within 6 h. All the degradation curves of atrazine obeyed pseudo-first-order kinetics (Fig. 1b). The atrazine

In this study, we demonstrate that ascorbic acid (AA) exhibited extremely high activity on persulfate (PS) activation (AA/PS) to produce SO4[rad]− and [rad]OH for the degradation of various organic pollutants, including atrazine, pentachlorophenol, alachlor, tetracycline, and chloramphenicol. Taken atrazine as a model natural organic micropollutants, we surprisingly found that the degradation rate constant of atrazine during PS activation in presence of AA was about 29 times larger than that in the absence of AA. The underlying mechanism of pe...
