TOMAC为载体的大块液膜法处理含镍废水

研究了三辛基甲基氯化铵（TOMAC）为载体的大块液膜体系处理含镍（Ⅱ）废水.应用正交实验考察了料液相中金属离子浓度、载体浓度、反萃剂浓度、料液相pH对镍（Ⅱ）迁移的影响.结果表明,镍（Ⅱ）迁移的最优方案为料液相中金属离子浓度为0.03mol/L,载体浓度为6%,反萃剂浓度为0.05mol/L,料液相pH为10.在最优条件下,迁移时间180min,迁移率可达53.92%.因素的影响主次为镍（Ⅱ）浓度〉料液相pH〉载体浓度〉反萃剂浓度.

Treatment of Nickel wastewater with bulk liquid membrane using TOMAC as carrier

The treatment of Nickel wastewater with bulk liquid membrane using TOMAC as carrier was studied. The effects of the concentration of Ni（ Ⅱ ） in feed phase, the concentration of carrier in membrane phase, the concentration of HCl in strip phase and pH value in feed phase on the transport of Ni （ Ⅱ ） were researched through orthogonal design. The results show that the transport rate of Ni（ Ⅱ ） can reach 53.92% under the optimal conditions of the concentration of Ni（ Ⅱ ） in feed phase, the concentration of carrier in membrane phase, the concentration of HCl in strip phase and pH value in feed phase were 0.03mol/L, 6M, 0.05mol/L and 10, respectively, when the transport time was 180 min. In addition, the order of the effects on the transport rate of Ni（ Ⅱ ） is the concentration of Ni（ Ⅱ ） 〉 pH value in feed phase〉 carrier concentration 〉 the concentration of stripping agent.
