摘要
作为有机物相对含量的指标之一,化学需氧量是水质评价的重要污染因子,直接影响评价结果,因此其监测数据的质量保证尤为重要。本文着重对分析测试中标准溶液浓度的选择、配制方法以及取样方式等细节问题提出了自己的见解。
COD is the important pollution factor for water assessment as one of the relative target of organic material, and impact the assessment result. So the quality of the monitoring data is very important. The article put forwards the opin- ions on the selection of standard solution concentration,compound method and sample mode.
