Abstract

In view of very low concentrations of metal ions present in effluents and streams, special types of electrolysers have been tried for the purpose. Investigations have been carried out using zinc containing effluent (160 ppm of zinc) under alkaline condition in a packed-bed electrolyzer and in batch recirculation system. Effect of flow rate and concentration of sodium hydroxide have been studied. It was observed that maximum removal efficiency of 98.75% was obtained at a flow rate of 180 l. hr-1 hr.-1with 0.1N sodium hydroxide as supporting electrolyte. At higher concentration of sodium hydroxide both the current and the removal efficiency is considerably reduced due to partial redissolution of zinc
