| Abstract: | 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. |
