摘要
研究了以HCl沉淀分离银 ,用ICP -AES法同时测定氰化镀银液样品中Cu ,Fe ,Pb ,Ni,Zn ,Sb的新方法。对影响测定的各种因素进行了较为详细研究 ,确定了实验的最佳测定条件。结果表明 ,方法的检出限为 0 0 0 3～ 0 0 2 5 μg/mL ,回收率为 92 3 %～ 10 4 8% ,RSD小于 3 44 %。方法准确、快速、简便 ,应用于氰化镀银液中杂质元素的测定 ,结果满意。
A chemical separation-inductively coupled plasma-atomic emission spectrometric(ICP-AES) method was established for the determination of Cu,Fe,Pb,Ni,Zn, and Sb in silver cyanide liquor The various factors affecting spectrum intensity were examined in details The optimum conditions for the determination were tested The detection limit of the method is 0 003-0 025μg/mL The recovery ranks from 92 3% to 104 8% RSD is less than 3 44% This method is accurate, rapid and convenient It is used in the determination of impurity elements in silver cyanide liquor with satisfactory results
