초록
흡착벗김전압전류법을 이용하여 게르마늄 분석을 하였으며, 리간드로는 Tannic acid를 사용하였다. 수집전위는 -0.2V, 수집시간은 60초, 평형시간은 20초, 주파수는 10Hz였다. 작업전극으로는 매달린 수은전극을 이용하였고 지지전해질로는 pH=4.5인 아세트산 완충용액을 사용하였다. 게르마늄의 분석을 위한 리간드의 알맞은 조건을 알아내었고 게르마늄 봉우리 전류에 대한 금속이온(납, 구리, 규소, 주석, 갈륨)의 영향에 대하여 조사하였다.
This is an analytical study of germanium by adsorption stripping squarewave voltammetry. Tannic acid was used as a ligand. The accumulation potential was -0.2V, accumulation time was carried out for 60 second under constant stirring, followed by a 20 second quiescent period, and frequency was 10Hz. A hanging mercury drop electrode was used as a working electrode and acetate buffer solution, pH=4.5, as supporting electrolyte. The proper conditions of ligand for germanium analysis was established. The effect of metal ions(lead, cupper, silicon, tin, gallium) on germanium peak was also studied.
