| 摘 要： | 文章利用电聚合法制备出银/乙二胺修饰电极,并研究H2O2在该修饰电极上的电化学行为,并考察实验条件的影响.实验结果表明:在pH6.7的磷酸盐缓冲溶液中,银/乙二胺修饰电极对H2O2具有良好催化还原作用,H2O2在修饰电极上产生一对较好的氧化还原峰,峰电位分别为Epa=0.344 V,Epc=-0.215 V.线性范围为2.0×10-5～8.0×10-4 mol.L-1,检出限为1.0×10-6 mol.L-1.用于样品中H2O2的测定,结果满意.

| Abstract: | In this paper,glassy carbon electrode modified with silver and ethylenediamine was prepared by electropolymerization,and the electrochemical behavior of electrode modified with nano-silver and ethylenediamine in hydrogen peroxide solution was studied and the best response conditions was detected. Experimental results showed that in the pH6.7 phosphate buffer solution,electrode modified with nano-silver and ethylenediamine had a good catalytic reduction effect on hydrogen peroxide,with the hydrogen peroxide ... |
