摘要
用ICP-OES对土壤中镍和铬进行分析,标准曲线的相关系数镍为0.9995、铬为0.9998,检出限镍为0.50mg/kg、铬为5.00mg/kg,国家标准样品的测定值在其保证值范围内,相对标准偏差镍为0.9、铬为0.7,加标回收率在95%～105%之间,准确度、精密度良好。
The determination of nickel and chromium on soil with ICP-OES has been studied.Theexperimental results are coefficient of standard curve for 0.9995 nickel,chromium is 0.9998,the detection limit is 0.50mg/kg,5.00mg/kg nickel chromium,national standard samples for the determination of value in the range of values,the relative standard deviation is 0.9,Ni Cr for 0.7,recovery rate in 95%～ 105%.The result is a great satisfaction.
