分光光度法测定磷含量的改进

Modification of Determining the Phosphorus with Spectrophotography in the Water

本文对用分光光度法测定水中磷含量时,试剂的酸度、试剂的浓度、试剂的用量和放置时间等影响显色反应的因素进行了探讨,改进了教学中的实验方法,结果满意。

The article discusses the chromogentic factors of the acidity,concentration,amount and time of the reagent,when the phosphorus is in determined the water with spectrophotometric method.It also puts forward a revised experimental method which provides a satisfactory result.
