| Abstract: | A gold nanoparticles modified glassy carbon electrode(NG/GCE) was prepared by electrodepositing.The electrochemical behavior of calcium dobesilate on the modified electrode was investigated in 0.05 mol/L H2SO4 by cyclic voltammetry.The NG/GCE showed an obvious electrocatalytic activity toward the redox reaction of calcium dobesilate and a new method for the determination of calcium dobesilate was established.On SWV curves,a linear dependence of oxidation current versus calcium dobesilate concentration was o... |
