摘要
提出了滤纸法测定悬浮物时,水样的酸碱度、取样量的多少对悬浮物测定有直接的影响。通过实验验证,对于偏酸、偏碱的水样用酸碱中和后再过滤即可消除影响,取样量应根据悬浮物的不同而定。
The acid-base degree of water sample and the sampling volume have direct impact on the determination of seston by the filter method.The acid and alkali water samples can be done neutralization reaction test,and then the impact can be eliminated.The sampling volumes are different according to the different sestons.
