Abstract
Gold electrodeposition onto a glassy carbon microelectrode is studied using an electrochemical amplification method. Taking the advantage that the electrochemical reduction of K2Cr2O7 has significantly higher reaction activity on gold electrode than carbon electrede,it is tentatively used to amplify the gold electredeposition current.The results show that there is a marked increase in current of gold electrodeposition in presence of K2Cr2O7 in comparison with that absent of K2Cr2O7.The electrochemical amplification method can be applied to study the electrodeposition of very in intial stage by choosing proper systems and improving experimental conditions.
