Abstract
The experimental use of chitosan(CTS) and vanillin Synthesis modified chitosan derivatives Schiff base(VCG) will drop it at a glassy carbon electrode formed on the surface of thin films,electronic referral through adsorption accumulation of Fe(CN)_6~(3-),so fixed on the electrode surface to the working electrode modified electrode, platinum electrode to electrode on the saturated calomel electrode as reference electrode,by cyclic voltammetry study of Fe(CN)_6~(3-)/VCG/GC modified electrode catalyst,quercetinous solutions.pH 6.0 in phosphate buffer solution,oxidation peak current and quercetin concentration 10~(-4)~10~(-2) mol/L with a good linear relationship between samples for the determination can obtain good achievement.
