摘要
采取强酸性阳离子交换树脂分离铜、磷,确定了交换分离的最佳条件,用ICP-AES测定,根据谱线强度大,信背比高的原则确定磷的最佳分析波长,当CCu/CP≤20时,磷的测定误差≤5.0%,满足了分析的要求,实验的相对标准偏差为2.17%—5.00%,相对误差为-9.1%—4.5%,表明该分析方法的精密度和准确度均较好。
The copper and phosphorus was separated by strong acid cation exchange resin,and the optimal conditions were confirmed,and the trace phosphorus was determined by inductively coupled plasma atomic emission spectrometry（ICP-AES）.According to the principle for large spectrum intensity and high signal to background,the optimal analytical wavelength of phosphorus was identified,when concentration ratio of copper to phosphorus was less than or equal to 20,the measurement error of phosphorus was less than or equal to 5.0%,that met the analytical need.RSD of the method was in the range of 2.17%—5.00%,and the relative error was between-9.1% and 4.5%.The results show that the analytical method has the good precision and accuracy.
