Abstract	Germanium(IV)-Morin 착물에 대한 네모파 양극벗김 전압전류법적 연구를 0.5 M 황산 지지전해질에서 수행하였다. Germanium(IV)-Morin 착물의 피크전위는 -0.606V vs. Ag/AgCl에서 나타났다. Germanium(IV)-Morin 착물의 피크전류 크기에 미치는 지지전해질의 황산 농도, Morin의 농도, 축적전위 및 축적시간의 의존성 등에 대하여 논의하였다. 또한, Germanium(IV)-Morin 착물의 피크전류 크기에 영향을 주는 금속양이온들의 방해효과도 조사하였다. 이 방법을 적용하여 축적시간을 60초로 하였을 때 Germanium(IV)의 검출한계는 3 76×10·-7 M(27 /L) 이었으며,0.4 mg/L(5.5×10 -6 M)의 Germanium(IV) 분석에 대한 상대표준편차(n=8)는 3.2%이었다. Square-wave anodic stripping voltammetry was applied to the germanium(Ⅳ)-Morin complex in 0.5 M sulfuric acid as a supporting electrolyte. The peak potential appeared at - 0.606 V vs. Ag/AgCl. Effects of sulfuric acid concentration, Morin concentration, accumulation potential, and accumulation time on the stripping peak current for the complex of germanium(Ⅳ)-Morin were studied. Interferences by other metal cations that affect on stripping peak current were also investigated. The detection limit was found to be 3.76×10-7 M(27 μg/L) for germanium(Ⅳ) using 60 seconds of accumulation time. The relative standard deviation (n=8) for 0.4 mg/L(5.5×10-6 M) germanium(Ⅳ) was 3.2%.
