초록

새로운 종류의 벗김전압전류법, 즉 전도된 촉매 벗김전압전류법 ($IC_tSV$)을 소개한다. 염산 용액에서 로듐-포름알데히드 착물은 역주사 동안에 환원전류 봉우리 즉 전도된 촉매수소 봉우리가 생긴다. 이 전도된 봉우리의 특징을 조사하고 이 봉우리를 분석 봉우리로 이용하여 결정한 검출한계는 $1.2{\times}10^{-10}M$ (축적시간 50초)이었다. 최적 실험 조건은 0.015% (W/V) HCHO-0.42 M HCl, 농축전위 -1.1 V, 주사속도 100 mV/s이다.

A new type of stripping voltammetry, inverted catalytic stripping voltammetry $IC_tSV$, is introduced. The rhodium-formaldehyde complex in hydrochloric acid gives an inverted catalytic hydrogen peak (reduction current peak during positive-going scan). The characteristics of the inverted peak were studied. By using the peak as analytical peak the detection limit of $1.2{\times}10^{-10}M$ Rh (50s preconcentration) can be reached at the optimal conditions: 0.015% (W/V) HCHO-0.42 M HCl; accumulation potential, -1.1 V; scan rate, 100 mV/s.
