Electrochemical Oxidation of Silver (Ⅰ) Salt

Ag(Ⅰ) 염의 전해산화
Duk Mook Kim

2M AgNO3 수용액을 백금이나 탄소 전극을 이용하여 비교적 높은 전류밀도에서 전해 산화하였다. 이 생성물을 산화력과 X-ray powder diffraction patterns, thermal analysis, 그리고 환원 곡선등을 구하여 Ag7O8NO3 임을 확인하고 끓는물에서 가수분해 하여 Alfa-product AgO보다 순도가 높고 비중이 큰 AgO를 얻을 수 있었다.

The anodic oxidations of the Silver(Ⅰ) / Silver(Ⅱ) / Silver(Ⅲ) system have been studied in aq. 2M AgNO3 solution with Platinum and Carbon electrodes. It has been found that Ag7O8NO3 can be produced at relatively higher current density. Deposited black Oxy-salt were analyzed with several methods such as oxidizing power, X-ray powder diffraction patterns, thermal analysis, and reduction curves. It decomposed to AgO upon being suspended in boiling water. AgO compound obtained from Ag7O8NO3 were purer and denser than Alfa-product AgO.
