零价铁降解水中的阿特拉津

Degradation of Atrazine in Water by Zero-valent Iron

摘要:

本文应用零价铁(Fe⁰)技术,以阿特拉津为目标污染物,考察了零价铁的效应,研究了不同零价铁投加量、不同溶液初始pH值等因素对阿特拉津降解效果的影响。结果表明,零价金属铁脱氯降解阿特拉津,随着金属铁质量的增加,阿特拉津的降解率也会增加;溶液初始pH值2～11时,阿特拉津降解率随其低pH值的增加而减小,可以促进零价金属铁的腐蚀,有利于阿特拉津降解。

Abstract:

In this study,the degradation efficiency of atrazine by iron was reported.The major affecting factors on atrazine degradation such as different iron,initial pH value of solution were studied.The results showed that the zero-valent iron has a significant effect on degradation of atrazine.With the increase in the quantity of iron,atrazine degradation rate increased.When initial pH of solution was between 2 to 11,atrazine degradation rate decreased as the pH rose because zero-valent iron corrosion promoted.
