摘    要:提出了利用溶剂浮选富集DDTC-Cu(Ⅱ)体系测定水样中痕量铜的方法(DDTC为二乙胺二硫代甲酸钠)。质量浓度的检出限为0.05ng·mL^-1,线性范围为0.0 ̄6.0ng·mL^-1,测定含Cu(Ⅱ)4.0ng·mL^-1的样品,相对标准偏差为0.85%,已用于天然水中Cu(Ⅱ)的测定。

关 键 词:溶剂浮选  光度法

Abstract:new method with the solvent floatation gether DDTCCu() system for determination of trace copper in water colmn is developed. The condition of the most pure determination if checked,and the trace copper in natural water is measured. The results of the test show the method has high sensitirity and precision.
Keywords:Solvent    floatation  photometric method  copper
