摘 要: | 含镍废水不仅造成镍金属的浪费,并且带来环境污染。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Ni~(2+)浓度等因素对Ni~(2+)的回收率的影响。实验结果表明:在电解时间240min,电流强度15A,Ni~(2+)质量浓度20g/L,电解温度50℃,p H值6,搅拌速率300r/min的条件下,Ni~(2+)的回收率为85.42%,电流效率为52.16%。

Abstract: | Wastewater containing nickel not only causes waste of nickel metal,but also brings environmental pollution. In this paper,nickel sulfate solution was used to simulate nickel-containing wastewater. The best anode material was determined to be rutheniμm-coated titaniμm 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 Ni~(2+) is 85.42%,and efficiency is 52.16% under the condition of 240 min electrolysis time,15 A amperage,20 g/L,Ni~(2+)concentration,50°C electrolysis temperature,6 p H and stirring rate of 300 r/min. |
