摘要:
藉金硫键将二苯基硫脲组装在金电极上,形成二苯基硫脲自组装膜电极.利用循环伏安法(CV)和微分脉冲伏安法(DPV),考察氧化还原指示剂在自组装膜上的电子传递过程,并运用离子通道理论探讨膜电极与醋酸根阴离子的作用机理.实验结果表明,二苯基硫脲自组装膜电极在1.0 mol.L-1,V(氯化钾)∶V(乙氰)为3∶2的混合底液中,随着加入醋酸根阴离子阴离子的增加,指示剂的氧化还原峰峰最流增大,峰形查逆性变好,且DPV峰电流与醋酸根阴离子浓度在0~0.07 mol.L-1范围内呈现线性关系.
Abstract:
Diphenylthiourea were assembled onto the gold electrode surface with Au-S bond to form a diphenylthiourea self-assembled monolayers(SAMs) Au electrode.The electron transfer process of the oxidoreduction-indicator had been studied by cyclic voltammetry(CV) and differential pulse voltammetry(DPV) methods and the interaction mechanisms of the self-assembled monolayer were discussed.Results showed that the curve shape of oxidation-reduction indicator was improved and the current increasing with the more adding of AC-in l.0 mol·L-1 KCl/CH3CN(volume ratio=3∶2) mixed solution.The linear relationship of the DPV currents and the concentrations means the SAMs electrode can be used in anion electrochemical recognition.
