氯离子、溴离子选择电极的制备及应用已有许多报告。本文介绍我们试制成功的731-C1、732-Br固态压片型离子选择电极及其性能测定。 (一)电极的制备与构造在不断搅拌情况下通高纯硫化氢气体于0.05M硝酸银溶液中,直至作用完毕,过滤沉淀,用去离子水洗涤沉淀,使溶液对Ag~+不发生沉淀反应。把洗涤干净的硫化银沉淀放在浓度为0.05M硝酸银溶液中,在剧烈搅拌下逐滴加入1:1的盐酸溶液,到盐酸溶液稍过量为止。用去离子水
Many reports have been made on the preparation and application of chloride ion and bromide ion selective electrodes. This article describes our tried-and-true 731-C1, 732-Br solid state pressure type ion-selective electrode and its performance measurement. (A) Preparation and construction of the electrode In the case of constant stirring through high-purity hydrogen sulfide gas in 0.05M silver nitrate solution until the action is completed, the precipitate was filtered, the precipitate was washed with deionized water, the solution did not precipitate Ag ~ + reaction. The clean silver sulfide precipitate placed in a concentration of 0.05M silver nitrate solution, was added dropwise with vigorous stirring 1: 1 hydrochloric acid solution to a slight excess of hydrochloric acid solution so far. Use deionized water
