摘要
采用一种新兴吸附技术—电容去离子技术(CDI),利用活性炭/离子交换树脂复合电极去除石煤空白焙烧—硫酸浸出液中的铝,考察了各工艺条件对钒、铝分离因数的影响。结果表明,当施加电压为2.0V、进料流量25mL/min、溶液初始pH 0.75、电极间距9mm时,对酸浸液中的铝的吸附量为422.4mg/g,钒、铝分离因数为28.3,钒、铝分离效果显著。
Aluminum was removed from blank roasting-acid leaching solution of stone coal with an emerging desalination technology-capacitive deionization （CDI） by ion exchange resin/activated carbon composite electrode.The effect of process conditions on separation factor between vanadium and aluminum was investigated.The results show that adsorption quantity of aluminum is 422.4 mg/g with separation factor of 28.3 under the optimum conditions including charging voltage of 2.0 V,feeding flow rate of 25 mL/min,pH value of 0.75,and electrode spacing of 9 mm.
