摘要
本文改用 一种新 的氯化亚 锡溶 液配 制 方法 ,增 加显 色 剂氯 化亚 锡 溶液 的浓 度, 延长 稳 定时间,在 测定时减 少显色剂 的用量 ,经对比实 验表明 ,该法灵 敏度、准确 度、精 密度 、溶 液的 稳定 性、显色效果 等均满 足环境监 测的规定
A new method for preparing the solution of tin chloride is described,by which the concentration of the tin chloride solution in the colour reagent can be increased with a longer stabilization time;the dosage of the colour reagent can be decreased during the determination.It is indicated through a comparative experiment that the sensitivity,accuracy,solution stability and developing effectiveness of the method can all meet the requirements of environmental monitoring.
