【Abstract】 おhe emulsion liquid membrane technique is applied to enrich the trace nickel and cadium in the wastewater.The rate of recovery reaches as high as 97%.The aqueous post enrichment is determined directly by the method of ICP-AES,which is simple,rapid and accurate.In general,ordinary metals,reaching fifty times the content of nickel and cadium,do not interfere.The result of nickel and cadium in the wastewater after going through determination processes is very much satisfactory.
