사각파형 벗김 전압 전류법과 순환 전압 전류법에서 적외선 광 다이오드의 간단한 전자 회로를 사용한 철의 정량을 연구하였다. 기존에 사용되는 작업 전극과 최적 분석 조건을 비교하였으며, 순환 전압 전류법의 결과는 보다 간단하며 정밀하였으며, 최적 조건에서 농도 범위는 0.1-0.8과 0.85-6.0 mg/L 이었다, 0.4 mg/L의 철 농도에서 15번 반복 측정한 상대 표준편차는 0.09%였으며, 최소 분석 검출 한계는 <TEX>$80{\pm}0.6{\mu}g/L$</TEX> 였다, 이결과는 폐수중의 철 정량에 응용하였다.
A simple electric circuit of an infrared photodiode electrode (IPDE) was utilized to monitor iron using square-wave (SW) anodic stripping voltammetry (SV) and cyclic voltammetry (CV). The optimum analytical conditions were determined and were compared with those of common working electrodes. The comparison showed that CV is more sensitive and convenient to use than the common voltammetry methods. At the optimized conditions, the working ranges of 0.1- to 0.8- and 0.85- to 6.0 mg/L iron was obtained. Relative standard deviation of 15 measurements of iron (0.4 mg/L) was 0.09%. The analytical detection limit was found to be <TEX>$80{\pm}0.6ug/L$</TEX>, which was applied to iron in waste water.
