英文摘要	应用方波溶出伏安法研究了芦丁在0.1mol.L-1HAc-NaAc缓冲溶液中于玻碳电极上的电化学行为.考察了溶液酸度、沉积电位、沉积时间等因素对芦丁方波溶出伏安行为的影响,优化了实验参数.结果表明,在pH3.0的HAc-NaAc缓冲溶液中,芦丁在-0.46 V产生溶出峰,峰电流与芦丁的浓度在5.0×10-8mol.L-1~1.0×10-6mol.L-1范围内呈现良好的线性关系,相关系数0.997 99,检测限1.1×10-8mol.L-1.可用于药剂中芦丁含量的测定.; The electrochemical behaviors of rutin(Rt) at glassy carbon electrode were studied by square wave stripping voltammeter in the presence of 0.1mol·L-1HAc-NaAc buffer solution(pH=3.0).The sensitive oxidation peak of rutin was observed and which potential peak is 0.46V(vs.SCE).The experimental parameters,such as pH value,deposition potential and deposition time were investigated and selected.The peak currents were proportional to the concentration of rutin in range of 5.0×10-8 mol·L-1~1.0×10-6mol·L-1,and the linear regression coefficient equaled 0.99799,the detection limit was 1.1×10-8 mol·L-1.This method was applied to the determination of rutin content in tablet with satisfactory results.; 作者联系地址：西华师范大学化学化工学院,西华师范大学化学化工学院,西华师范大学化学化工学院,西华师范大学化学化工学院四川南充637002,四川南充637002,四川南充637002,四川南充637002; Author's Address: Institute of Chemical Engineering,China West Normal University,Nanchong 637002,Sichuan,China
