Abstract
In this study, the optimum analytical condition of Differential pulse Voltammetry for the polymeric Sodium Alginate was studied and its reduction funtional groups were confirmed using Cyclic Vol-tammetry and IR spectroscopy. Optimum conditions were as followed; mercury drop size : medium size, accumulation time : 60sec, accumulation potential : -0.20V vs Ag/AgCl, scan rate : 100mV/sec, supporting electrolyte : 0.10M
본 실험에서는 고분자 상태의 Sodium Alginate를 시차펄스 전압전류법을 이용하여 최적의 분석조전을 조사 연구하였고, 먼저 고분자 상태인 Sodium Alginate를 순환전압전류법과 IR로 환원 작용기를 확인하였다. 수은방울크기 (medium size), 수집시간(60초), 수집 전위 (-0.20V vs Ag/AgCl), 주사속도(100mV/sec), 지지전해질(0.10M
