摘要
在水和废水的监测过程中,测定悬浮物的含量具有重要的意义。但在实际的监测分析过程中,往往会造成悬浮物含量明显偏低(有时甚至出现负值)或明显偏高的情况。为此提出了该系统误差产生的原因及其消除方法,同时提出了行之有效的实验室悬浮物测定的质量控制方法。
It is of important significance to determine suspended substance in monitoring water and wastewater. However,in actual determination,the content of suspended substances is obviously lower than the real content(even negative value appears sometimes) or higher than the real content,owing to analyst's negligence. The reason for which systematic errors appear and their elimination are put forward. At the same time,an effective method of the quality control of the determination of suspended substances in laboratory is proposed.
