摘要: 为了综合处理水中的阿特拉津，以绿茶萃取液为还原剂，以活性炭为载体，采用液相还原法绿色合成了纳米铁/活性炭复合材料，研究了活性炭投放量、阿特拉津的初始浓度、溶液初始pH值及反应时间对阿特拉津去除率的影响，探讨了不同影响因素下阿特拉津的降解动力学。结果表明：阿特拉津降解反应近似符合二级反应动力学，反应速率常数0.001 08~0.002 73 L·（mg·min）-1。在纳米铁/活性炭复合材料去除阿特拉津过程中，纳米铁的还原和活性炭的吸附共同作用。

Abstract: To address the atrazine contamination of water,green tea was employed as a reducing agent,and nano-zero-valent iron/active carbon composites were prepared by green synthesis. The effects of the active carbon dosage,initial atrazine concentration,initial pH of the atrazine solution,and residence time on the atrazine removal rate were investigated,and the atrazine degradation kinetics were studied. The results show that the atrazine degradation reaction follows second-order reaction kinetics,and the reaction rate constants are between 0.001 08 and 0.002 73 L·(mg·min)-1. The atrazine removal process depends on the interaction between nano-zero-valent iron reduction and active carbon adsorption.
