A Study on Removal of Fenitrothion by Integrated Zero-valent Iron and Granular Activated Carbon Process

This study investigated the decomposition of fenitrothion in Smithion, which is applied on the golf course for pesticide, by the integrated Zero-valent iron(ZVI) and Granular activated carbon(GAC) process. First, the removal efficiencies of the fenitrothion by ZVI and GAC, respectively, were investigated. Second, the removal efficiencies of the fenitrothion by the integrated ZVI and GAC were investigated. The removal efficiencies of fenitrothion by ZVI were higher than those of TOC. The removal efficiencies of fenitrothion and TOC by GAC were similar. As the dosages of ZVI and GAC were increased, the removal efficiencies of fenitrothion and TOC increased. However, as the dosages of ZVI for pretreatment were increased, the adsorptions of fenitrothion on GAC were hindered.
