分光光度法测定水中铍的最佳条件选择

The Best Condition on Spectrophotometric Determination of Beryllium in Water.

本文对分光光度法测定水中铍的最佳测定条件进行了研究和探讨。在方法对比实验的基础上，选择了最适宜的方法，并进行了各种条件实验，对某些实验条件进行了改进。特别是对阴离子的干扰，提出了有效的消除方法。改进后的实验方法，显色稳定，重现性好，灵敏度高，摩尔吸光系数达１．０１×１０５Ｌ／ｃｍ·ｍｏｌ。

The essay contacts with research and discussion on the best determention condition of Beryllium in water.Chose the best appropriate method on the base of the compare experiments and improve some conditions of experiment.Find the good way to eliminate the desturbing of Anion.The improved method have stable collor showing,better repearment and sensitivity .The molar absorptivity is 1 01×10 5L/cm·mol.
