摘要
文章通过采用国家标准《水质-总磷的测定,钼酸铵分光光度法》GB11893-1989,对水体中的总磷进行了精密度偏性试验。试验表明,该监测项目各项指标均符合实验室内部质量控制要求,所测数据合理,整个分析过程均在质量控制范围之内。
According to GB11893-1989 Water quality-Determination of total phosphorus-Ammonium molybdate spectrophotometric method of the national standard,this paper conducted the precision bias test for TP in water body. The test shows that all indicators of this monitoring project meet the demands on laboratory internal quality control,all data are reasonable,and the whole analysis process is within the quality control scope.
