摘要
Abstract
A new and simple method using nanometer-sized ZrO2 as a solid phase extractant coupled with spectrophotometry was proposed for determination of copper( Ⅱ ).The nanometer-sized ZrO2 was prepared through sol-gel method.And the adsorption pH curve、adsorption capacity was obtained.It was found that the fraction of adsorbed Cu2+ was more than 95％ under pH 9.0-11.0, and 0.7 mol · L-1 HC1 was sufficient for complete elution.Nanometer-sized ZrO2 possesses a significant capacity (3.1 mg/g) for the adsorption of Cu2+.The fraction of Cu2+ absorbed on the recycled nanometer-sized ZrO2 still reached quite a high level, which showed that the nanometer-sized ZrO2 was reusable in practice.The study on interference of co-existing ions indicated that ZrO2 had high selectivity for copper ion.The method was applied to enrichment of trace copper ( Ⅱ ) in water samples with satisfactory results.关键词
