中文摘要:

      应用ICPAES法对环境水样中Cd、Cr、Cu、Ni、Pb、Zn等6种微量元素进行直接测定.考察了环境水样中钙、镁离子对测定的影响.通过对国标样品及实际样品的测定,加标回收实验,建立了简便、快速、准确、稳定、重现性较好的ICPAES法测定环境水样中6种微量元素的分析方法.

英文摘要:

      After an investigation in the influences of Ca and Mg on the determination and making choice of appropriate working condition for the instrument, a direct determination is made for Cd,Cr,Cu,Ni,Pb and Zn in environment water samples by ICP AES. An analytical method is proposed to determine the six trace elements in environment water samples by ICP-AES, by means of determing the standard samples and unknown samples and comparing to both results of experiment. This method shows some superiorities in convenience, accuracy, promptness, stability and re appearance.
