水质悬浮物测定中出现负误差现象的探讨

Discussion on the Phenomenon of Negative Error Existing in the Determination of Suspended Solids in Water

论文研究了悬浮物测定中因滤膜所含水溶物性物质而造成的负误差影响。对滤膜使用浸泡—抽滤的方法进行预处理,可有效解决较清洁水样悬浮物测定的负值现象,准确地反映了水样中悬浮物的实际浓度。

This paper studies negative error impact caused by water soluble property in membrane in the determination of suspended solids. Using the method of soaking-suction filter to preprocess membrane filter, which can effectively solve the negative phenomenon in clean water samples determination of suspended solids, accurately reflect the actual concentration of suspended solids in water samples.
