| 中文摘要 |
| 研究水和废水中多种元素ICP-AES的通用分析方法,探讨了样品的前处理过程、最佳实验条件的选择、干扰的判断和校正及在整个分析过程中应注意的问题等。实验结果表明:此方法准确可靠,测定值基本能很好地与质控样的标准值相符合,加人回收率多在90%—110%范围内,精密度多低于5%,检出限为0.l—100μg/L,线性分析范围达4—6个数量级。该方法简便快速易于掌握,可同时进行多元素分析。 |
| 英文摘要 |
| A general ICP-AES method for simultaneous multielement analysis of water or wastewater was studied and samples pretreatment process,experimental condition optimazing,interference judging,correction and the aspects needed for paying attention during the analysis were discussed. The results showed that analytical data were accurate,reliable,and coincident with the standard values of certified reference samples with a recovery of 90%—110%. The overall relative standard deviation is within 5%. The detection limits were 0.1—100μg/L. The calibration curve has a wide linearity range of 4—6 orders of magnitude. |
