摘要
采用水处理中常用的氧化剂高锰酸钾对内分泌干扰物17α-乙炔基雌二醇(EE2)进行去除研究,考查不同高锰酸钾浓度、EE2浓度、pH和离子强度等对EE2去除效果的影响。试验结果表明高锰酸钾可以有效去除EE2,去除率达到90%以上。EE2的去除率随着高锰酸钾浓度的增加而增大。反应前期,去除随着EE2初始浓度的增加而加快,反应后期则影响不大。偏中性和碱性时有利于EE2的去除。试验浓度范围内,EE2的去除和离子强度、有机物的含量呈正线性关系。
Potassium permanganate,a widely applied antioxidant in water treatment,was used to remove endocrine disrupting chemicals-17α-ethynyestradiol（EE2）.The effects of potassium permanganate dosage,EE2 concentration,pH,and ionic strength on EE2 removal were investigated.The results showed that potassium permanganate could remove EE2 effectively,and the removal rate of EE2 was more than 90%.The removal rate of EE2 increased with the increasing of dosage of potassium permanganate.In the early reaction,the removal rate of EE2 accelerated with the increasing of initial EE2 concentration.However,this phenomenon was not obvious in the latter stage of the reaction.The removal rate in partial neutral and alkaline was propitious to EE2 removal.In the range of the test concentrations,the removal rate of EE2 showed positive linear relationship with the concentrations of ionic strength and organic matter.
