In this study, we demonstrate that pyrite (FeS 2) can more effectively activate PS than the commonly used FeSO 4 for atrazine degradation. When 3.0 mM of PS and 4.2 mM of iron salts were used, the atrazine degradation efficiency of FeS 2 /PS was 1.4 times that of FeSO 4 /PS, while the amount of consumed PS in case of FeS 2 was only 53% of that ...
