摘要
采用电感耦合等离子发射光谱法同时测定水中的锰、锌、铅、铬、镍等多种金属离子.回收率在93 2%～107 0%之间,线性相关系数大于0 999,相对标准偏差介于0 13%～1 15%,测定灵敏度、精密度和准确度均满足有关水质分析标准要求.该方法具有样品前处理简单,干扰少,测定快速准确,可进行多元素同时分析.
This paper discusses the determination of Mn,Zn,Pb,Cr,Ni, etc.in water with ICP-AES(American Perkin-Elmer).The recoveries of elements are 93.2%～107% and linearity correlation r>0.999 and the relalive standard deviation(RSD) are 0.13%～1.15%. The method has the advantages of excellent sensitivity, precision, accuracy and simplicity of sample pretreatment, The interferences were low. It can meet demands of concerning standards for water quality analysis.
