进行了仪器分析条件试验,选择了仪器使用参数;进行了微量元素的分离、富集试验,保证检测准确度;进行了铜、锌、镍基体和其它共存离子的干扰试验,制定了消除干扰措施;进行了溶液酸度、试剂用量试验,合理选择加入量。适于不同浓度的4条工作曲线线性好。大量试验数据统计分析表明:该方法精密度良好、准确度很好。
The conditions of instrument analysis were tested and the instrument parameters were selected. The separation and enrichment tests of trace elements were carried out to ensure the accuracy of detection. The interference experiments of copper, zinc, nickel matrix and other coexisting ions were carried out and the interference elimination measures ; The solution acidity, reagent dosage test, a reasonable choice of dosage. 4 for different concentrations of the working curve of good linearity. The statistical analysis of a large number of experimental data shows that the method has good precision and good accuracy.
