摘要(Abstract):
采用一种电化学技术去除模拟工业水中的Cd(2+).单壁碳纳米管钛网电极被用做阴阳极,考察不同电极组合、溶液pH、应用电压和电解质浓度对Cd(2+).单壁碳纳米管钛网电极被用做阴阳极,考察不同电极组合、溶液pH、应用电压和电解质浓度对Cd(2+)去除率的影响.实验结果表明,阳极为Ti Net,阴极为SWCNTs@Ti Net,溶液pH为8.0,应用电压为2.5 V,电解质质量浓度为20.00 g·L-1为Cd(2+)去除率的影响.实验结果表明,阳极为Ti Net,阴极为SWCNTs@Ti Net,溶液pH为8.0,应用电压为2.5 V,电解质质量浓度为20.00 g·L-1为Cd(2+)去除的最佳实验条件.XPS和SEM结果表明,Cd(2+)去除的最佳实验条件.XPS和SEM结果表明,Cd(2+)的去除包括了在阴极上生成Cd(OH)_2和电吸附在阴极SWCNTs上.最高去除率可达90%左右.
