阳极铜中铜含量的测定

The Determination of Copper Content in Anode Copper

阳极铜样品用(1+2)硝酸溶解后,定容500 mL,分取50 mL,浓缩体积约10 mL,硫氰酸钾浓度(400g/L),用Na_2S_2O_3标准溶液滴定。实验证明,该方法操作简便、准确度和精密度都能满足生产分析要求,可以应用于阳极铜中铜的检测分析过程中。

Anode copper sample was dissolved by nitric acid（1＋2）、and diluted to 500 mL,taken 50 mL and concentrated to 10 mL,potassium thiocyanate concentration（400 g/L）and titration with Na_2S_2O_3 standard solution.Experimental results show that the method is simple,accurate and precise,and can be applied to the detection and analysis of copper in anode copper.
