Improvement function of CTAB over extraction rate of Cr(VI)

ZHANG Xue-qiao~(1,2),YAO Bing-hua~2,YANG Yi-jin~1,ZOU Chang-wu~1,DING Heng-kang~1(1.Dept.of environment Engineering,CUIT,Chengdu 610225,China;2.Xi'an University of Technology,Xi'an 710048,China)  
The effect of extraction rate of Cr(VI) with the addition of CTAB in the system,kerosene as solvent and TBP as extractant is investigated.The result shows that the surfactant CTAB can extract Cr(VI) efficiently that the ratio of removing Cr(VI) is up to 98% under certain conditions.Applied the system to the electroplating wasterwater the extraction rate of Cr(VI) is more than 90%.
