胶束强化超滤处理阿特拉津的研究

TREATMENT OF ATRAZINE BY MICELLAR-ENHANCED ULTRAFILTRATION

常规处理工艺并不能有效去除水中的环境内分泌干扰物质。研究采用十二烷基硫酸钠(SDS)为表面活性剂对阿特拉津进行增溶,并采用聚砜超滤膜和SDS胶束强化超滤处理阿特拉津。考察了SDS浓度、操作压力、无机盐、β-环糊精和烷基多苷(APG)等因素对工艺的影响。结果表明,胶束强化超滤对阿特拉津的去除率可达80%以上,无机盐、β-环糊精、APG和SDS的复配可以提高阿特拉津的去除率。

EDCs are not removed effectively by using traditional water treatments. The solubilization capacity for atrazine has been investigated with sodium dodecyl sulfate( SDS) as surfactant and micellar-enhanced ultrafiltration( MEUF) was used to treat atrazine with polysulfone membrane and SDS. The influence of treating parameters were investigated,including the concentration of SDS,operating pressure,inorganic salt,β-cyclodextrin and Alkyl polyglycosides( APG). The results show that MEUF has a great performance on the removal of atrazine. The removal efficiency of atrazine can be over 80%. The coexistence of inorganic salt β-cyclodextrin and APG can increase the removal efficiency of atrazine.
