Abstract:

Althrough using the gravimetric method to determine the suspended solid in the water samples has an advantage of high accuracy, but it has evident disadvantages, such as long determination time and low working efficiency. An amount of experiments have been made, and the result indicates that the spectrophotometric method is a simple and practical substituted method.

Key words: suspended solid, spectrophotometry, wastewater treatment

摘要：

利用重量法测定水样中的悬浮物具有准确度高的优点,但存在测定时间长、工作效率低等不足。作者经过大量的实验,认为分光光度法测定悬浮物是一种简单易行的替代方法。
