【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。更多还原

【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.更多还原
