胶团强化超滤处理水中阿特拉津的研究

Study on Removal of Atrazine in Water by Micellar-enhanced Ultrafiltration

采用胶团强化超滤去除水中阿特拉津。考察了表面活性剂、pH、操作压力、操作时间以及温度对阿特拉津去除效果的影响。结果表明,胶团强化超滤法能有效去除水中阿特拉津,最佳工艺条件为:采用分子量为5 000 Dalton的聚砜中空纤维膜、SDBS浓度为8.00 mmol/L、压力为0.15 MPa、pH为10、温度为25℃。在此条件下,初始浓度为10mg/L的阿特拉津截留率为84.7%。

Micellar-enhanced ultrafiltration（MEUF） was a new membrane water purification technology combinating solubilization of surface active agent and ultrafiltration membrane separation performance.Atrazine was used as target pollutants while SDBS was used as additional solvent,intercepting atrazine through MEUF.When the operating pressure was set at 0.15 Mpa and SDBS concentration was set at 8.00 mmol/L,pH was set at 10,the temperature was 25 ℃,the intercepting rate of atrazine turned out to be 84.7%.
