滤膜法与滤纸法测定水和污水中悬浮物的比对研究

摘要

In environmental monitoring of all surface water and the vast majority of enterprises sewage,sus-pended solids (SS)must be measured items. The experimental data in the analysis of samples in different categories of membrane filter method and filter method to compare the research from two aspects of preci-sion F test,significant T test,experiments show that measuring time shorter membrane filter method,the in-terference degree less.%悬浮物（SS）是在环境监测中所有的地表水及绝大部分企业污水的必测项目。该文从精密性F检验、显著性T检验2个方面对滤膜法和滤纸法在不同的水样类别分析中的实验数据进行比对研究，实验证明滤膜法测定时间更短，受干扰程度较少。
