摘要
用计时库仑法、常规脉冲伏安法、毛细管电荷曲线,以及循环伏安法研究了TeO_3^(2-)在1M NaOH溶液中在悬汞电极上的电化学行为。实验表明TeO_3^(2-)在悬汞电极表面呈强吸附。依据在各种实验条件下的实验结果,讨论了TeO_3~2的吸附对电化学响应的影响并讨论了电极反应机理。计算了电极反应物在悬汞电折上的吸附量。
Using chronocoulometry, normal pulse voltammetry, electrocapillary curve and cyclic voltammetry studies electrochemical behaviour of TeO_3^(2-) on the hanging mercury drop electrode (HMDE) in 1M NaOH. Experiments indicate that electrode reactant TeO_3^(2-) strongly adsorbed on the surface of HMDE. According to experimenial results at different test conditions, discussed the effect of adsorption of TeO_3^(2-) on the electrochemical response and the electrode reaction mechanism, calculated the adsorbance of electrode reactant on HMDE.
