引言镉铜合金中镉的测定,一般都用极谱分析和光谱分析方法。我们采用二苯硫卡贝松氯仿溶液在氢氧化钠的碱性溶液中萃取进行分光光度测定,获得了满意结果。试剂和仪器1 标准镉溶液:以硝酸溶解高纯金属镉(99.99%),准确稀释配成每毫升含镉10微克的溶液。2.5%的盐酸羟胺溶液。3.20%的酒石酸钾钠溶液。4.20%的氢氧化钠溶液。
Introduction Determination of cadmium in cadmium and copper alloys, are generally polarographic and spectral analysis methods. We use diphenyl sulfide carbethonium chloroform solution extraction in alkaline solution of sodium hydroxide for spectrophotometric determination, and obtained satisfactory results. Reagents and Instruments 1 standard cadmium solution: nitric acid dissolved high purity metal cadmium (99.99%), accurate dilution dubbed 10 micrograms per ml of cadmium solution. 2.5% hydroxylamine hydrochloride solution. 3.20% potassium sodium tartrate solution. 4.20% sodium hydroxide solution.
