电解法处理含镍废水的研究摘要:含镍废水不仅造成镍金属的浪费,并且带来环境污染
本文通过配制硫酸镍溶液模拟含镍废水,采用电解法确定最佳阳极材料为钌涂层钛板,并研究了电解时间、电流强度和 Ni2+浓度等因素对 Ni2+的回收率的影响
实验结果表明:在电解时间 240 min,电流强度 15 A,Ni2+浓度 20 g/L,电解温度 50 oC,pH 值 6,搅拌速率 300 r/min 的条件下,Ni2+的回收率为 85
42 %,电流效率为 52

In this paper, nickel sulfate solution was used to simulate nickel-containing wastewater
The best anode material was determined to be ruthenium-coated titanium plate by electrolytic method
The effects of electrolysis time, current intensity and nickel ion concentration on Ni 2+ recovery were studied
The experimental results show that the recovery rate of Ni2+
