本文研究了在0.01mol/dm~3 NaOH溶液中2-(5′-溴-2′-吡啶偶氮)-5-二乙氨基苯酚在汞电极上的吸附性、吸附量与吸附富集时间、吸附物浓废的关系。发现表面反应是可逆地进行的,峰电流与富集时间、扫描速度、浓度、吸附量的关系与理论一致,实验得到反应电子数与氢离子数是2。得出的反应机理是分子中偶氮基的还原反应。
In this paper, the adsorption of 2- (5’-bromo-2’-pyridylazo) -5-diethylaminophenol on mercury electrode in 0.01mol / dm ~ 3 NaOH solution was studied. The adsorption capacity and adsorption time , Adsorbate the relationship between thick waste. The surface reaction was found to be reversible. The relationship between peak current and enrichment time, scanning speed, concentration and adsorption capacity was consistent with the theory. The number of reaction electrons and hydrogen ions was 2. The resulting reaction mechanism is the reduction of azo groups in the molecule.
