Title: Flow injection analysis of ascorbic acid at a methylene green chemically modified electrode
Author(s): Yu, Ai-Min; He, Chun-Xiang; Zhou, Jie; Chen, Hong-Yuan
Abstract: In flow injection analysis (FIA) of ascorbic acid, methylene green (MG) modified carbon paste electrodes showed high catalytic activity and stability, reducing the oxidation overpotential by 400 mV. The linear response range was over 3 orders of magnitude and the detection limit was 1 X 10^-8 mol/L eq. 0.25 pmol with S/N = 3. The influence of various experimental conditions was explored for optimum analytical performance.
