| Abstract: | The electrocatalytic oxidation behaviors and electrochemical determination of glutathione(GSH) were investigated at nano-TiO2-caffeic acid modified carbon paste electrode(nano-TiO2-CFA/CPE).The experimental results indicated that GSH showed a very poor electrochemical response at CPE and nano-TiO2/CPE,but GSH at nano-TiO2-CFA/CPE exhibited a better electrocatalytic activity than that at CFA/CPE.The kinetic properties of GSH were discussed at nano-TiO2-CFA/CPE by cyclic voltammetry(CV) and chronoamperometry(... |
