摘要
对水质悬浮物的测定方法进行了探讨。通过控制取样体积,使地表水和低粘度废水在滤纸上的悬浮物量≤50.0 mg,而高粘度废水在滤纸上的悬浮物量≤20.0 mg,则样品在烘干1 h与烘干2 h后恒重分析结果相同。
A study on the method to determine the content of suspended materials in water is conducted. The weight of suspended materials captured by filter paper is controlled as equal to or less than 50. 0 mg for the surface water or low viscosity wastewater, and 20. 0 mg for the high viscosity wastewater. The experiment shows that the result of analysis on constant weight obtained from 1-hour drying is as same as that from traditional 2-hour drying.
