饮用水检验中标准溶液使用问题分析

Analysis of Problems of Standard Solution Application in Drinking Water Determination

总结水质检测工作中标准溶液使用存在的问题,主要包括校准用标准溶液和标准参考溶液混用,标准溶液稀释方法有误,选择、储存、恒温、核查等。标准溶液的合理选择、有效管理及正确使用才能保障分析结果的准确性。在实际工作中,应加强标准溶液的管理及使用培训,提高分析人员的综合素质。

Problems of standard solution in drinking water determination are summarized,which mainly includes confusion of use between standard calibration solution and standard reference solution,incorrect dilution method of standard solution,and selection,storage,constant temperature,verification of standard solution.Only reasonable selection,effective management and correct use of standard solutions can ensure accuracy of analysis results.In practical work,management and use training of standard solution should be strengthened to improve comprehensive quality of analysts.
