胶束强化超滤技术处理含低浓度Ni^2＋废水

TREATMENT OF WASTEWATER CONTAINING LOW CONCENTRATION OF Ni^(2+) BY MICELLAR-ENHANCED ULTRAFILTRATION PROCESS

以表面活性剂SDBS为吸附载体,研究了胶束强化超滤(MEUF)对低浓度放射性废水中的金属离子核素Ni2+的处理效果。研究表明,在表面活性剂浓度为1.0mol·L-1、溶液pH为9时,MEUF对Ni2+的截留率达到95%,表明了MEUF在低浓度放射性废水中良好的应用前景。

This paper focused on the treatment of the Micellar-Enhanced Ultrafiltration（MEUF） process to the metal iron Ni2＋,which is the mainly existence in low-level radioactive wastewater.The surfactant SDBS was chosen as adsorption carrier.The results indicated that the rejection ratio of MEUF was up to 95% when the surfactant concentration was 1.0 mol·L^-1 and the pH value of the solution was adjusted to 9.0.This research reflected the superiority of MEUF process and the feasibility of its usage in low-level radioactive wastewater treatment.
