摘要：

The performance of cells with reticulated vitreous carbon cathodes for the removal of low levels of copper ions from aqueous, acidic sulphate media is described. During the batch recirculation of nitrogen-sparged, sodium sulphate solutions, pH 2, the copper ion concentration may be reduced from 10 p.p.m. to < 0.5 p.p.m. or from 2.5 p.p.m. to < 0.1 p.p.m. with overall current efficiencies of 84% and 42%, respectively. The influence of solution flow rate through the cathode and the choice of the grade of the reticulated carbon is discussed. The removal of copper ions from solutions of low ionic strength, saturated with air and/or containing chloride ion is also investigated.
