纳米TiO2光催化降解毒死蜱的影响因素研究
Study on influence factors of chlorpyrifos degradation using TiO2
摘要
Abstract
The influence factors of chlorpyrifos degradation using TiO2 through high-pressure mercury lamp were investigated. Concentrations of chlorpyrifos were determined with HPLC. The results showed that the concentration 50-100 mg/L TiO2 was the optimum. Significant positive correlation was found between lower concentrations 5-20 mg/L of chlorpyrifos and degradation rate, while negative correlation with higher concentrations of 20 - 80 mg/L. The degradation kinetics of 10 mg/L chlorpyrifos followed the first order reaction. Different pH decreased below pH 7 after photocatlytic reaction,and alkaline conditions chlorpyrifos was favorable to the degradation.关键词
