怎样报水质分析结果,这是大家所关心的问题,例如某一项目应报告至小数后几位,保留几位有效数字等,这方面的文章不多见,意见也不尽一致,各实验室的要求也不一样。计量认证评审内容中关于“检测工作”第7条规定:“检测数据的有效位数和误差表达方式应符合有关误差理论的规定”。笔者就常用的重量法、滴定法、分光光度法、电极法、原子吸收法,举例说明怎样报水质分析结果。
How to report the results of water quality analysis is an issue of concern to all. For example, a project should report to the last few decimal places and retain a few significant figures. Articles in this area are rare and their views are not consistent. The laboratories The requirements are not the same. Article 7 of the contents of the accreditation of measurement accreditation on “testing work” stipulates that “the effective number of bits of the test data and the error expression shall comply with the relevant error theory.” I used the weight method, titration, spectrophotometry, electrode method, atomic absorption method, an example of how water quality analysis results reported.
