硫化银溶度积小(10~(-51)),对氧化剂、还原剂稳定,导电性能又好,它是较好的电极活性膜材料,用其可制或Ag~+、S~-离子选择电极。Tong-Ming-Hseu等评述了硫化银膜电极的灵敏度、选择性、响应特性及研究其分析应用。Vesely等用过量Ag~+或过量硫制硫化银沉淀,做成不同的电极,它们用于测定PAg时和PS时只有CN-和Hg(Ⅱ)干扰。Popescu等制成了硫化银陶瓷离子选择电极,并研究了它对Ag~+,S~-离子的响应特性,硫化银膜制造条件Ag~+对响应的影响,以及Ag~+的检出极限,电极的氧化还原特性等。我国
Sulfide solubility product small (10 ~ (-51)), the oxidant, reductant stability, good electrical conductivity, it is a good electrode active membrane material, with its system can be made of Ag, +, S ~ Select the electrode. Tong-Ming-Hseu et al. Reviewed the sensitivity, selectivity, response characteristics and their analytical applications of silver sulfide film electrodes. Vesely et al. Used excess Ag ~ + or excess sulfur silver sulfide precipitates to make different electrodes. They were used to determine only CN- and Hg (II) interferences at PAg and PS. Popescu made silver sulfide ceramic ion selective electrode and studied its response to Ag ~ +, S ~ - ions, silver sulfide film manufacturing conditions Ag ~ + response, and the detection limit of Ag ~ + , Redox characteristics of the electrode and the like.
