金的分光光度分析已有很多文章和专著.我们在前人工作的基础上,实验了疏基棉分离金以及4,4’双二甲基胺二苯甲硫酮(TMK)与十二烷基苯磷酸钠(SDBS)表面活性剂分光光度法水相测定金的条件.并以拟定的方法进行矿石中金的测定.结果令人满意.实验部分一、主要试剂及仪器0.01%TMK乙醇溶液;0.005%TMK乙醇溶液(由0.01%TMK用乙醇稀释制备);0.28%SDBS水溶液;4μg/ml金标准溶液;pH4.5醋酸—醋酸钠缓冲溶液:取32克Na
There are many articles and monographs on the spectrophotometric analysis of gold.On the basis of our predecessors’ work, we have studied the effect of sparse base cotton separation gold and 4,4’dimethyl amine diphenyl methylthione (TMK) and dodecane Sodium phenyl phosphate (SDBS) surfactant spectrophotometric method for the determination of the aqueous phase of gold, and the proposed method for the determination of gold in ores.The results are satisfactory.Experimental Part I. The main reagents and equipment 0.01% TMK ethanol solution ; 0.005% TMK ethanol solution (diluted with 0.01% TMK in ethanol); 0.28% aqueous SDBS; 4 μg / ml gold standard solution; pH 4.5 acetic acid-sodium acetate buffer solution: 32 g Na
