Abstract
A stripping voltammetric scheme for the determination of osmium, based on the adsorptive accumulation of osmium in the presence of hydroxylamine, was described. Cyclic voltammetry was used to characterize the redox and interfacial processes. Optimal experimental conditions were found to be a stirred 0.05M hydroxylamine hydrochloride solution(pH 1.8), accumulation at -0.65V for 60s, and a differential pulse mode with a scan rate of 10mV/s. The detection limit was
히드록실아민 존재하에서 오스뮴(IV)의 벗김 전압전류법적 정량법을 연구하였다. 가장 좋은 조건은 다음과 같다: 히드록실아민 0.05M, pH 1.8, 누적전위 -0.65V, 누적시간 60초, 주사속도 10mV/s. 이 조건에서 검출한계는
