Abstract

Germanium(IV) was determinated in perchloric acid supporting electrolyte solution containing catechol derivates 3.4-dihydroxy benzoic acid, 3.4-dihydroxy benzaldehyde, adrenaline by hanging mercury electrode(HMDE) of anodic stripping polarography. And then to apply this experimental method for determination of germanium(IV) in natural samples. Germanium(IV) was determinated $300{\mu}g/L$ in ginseng and $210{\mu}g/L$ in mineral water.

Catechol의 유도체인 3, 4-dihydroxybenzoic acid, 3, 4-dihydroxybenzaldehyde, 그리고 adrenaline을 사용하여 게르마늄과 착물을 형성시킨 후 Anodic Stripping Polarography로 정량한 후, 천연물 중의 게르마늄 정량에 적용시켜 분석한 결과 인삼에서 $300{\mu}g/L$, 광천수에서 $210{\mu}g/L$를 검출할 수 있었다.
