【摘要】 本工作用恒电位方波法,分别测量了在浓度为120g/L NaOH溶液中,含有不同浓度锌酸盐镀锌用的有机表面活性剂:DE、DPE—Ⅲ、KR—7和ZB—80以及DE+DPE—Ⅲ、DPE—Ⅲ+KR—7、DPE—Ⅲ+ZB—80在悬汞电极上的微分电容——电位曲线,从而比较了上列各种有机表面活性剂在悬汞电极上的吸附电位范围,表面活性大小和吸附机理。更多还原

【Abstract】 In this research, by potentiostatic square wave methods, We have respectively measured some organic surfactants in Zincate Znic-plating solution of different concentrations, ie DE, DPE—Ⅲ, KR—7, ZB—80, DE+DPE—Ⅲ, DPE—Ⅲ+KR—7 and DPE—Ⅲ+ZB—80, and Obtained the differential capacity—potential curves of these organic surfactants in 120g/L NaOH solutions on hanging mercury electrode. From these curves, we have compared with the ranges of adsorption potential, the strong or weak of adsorpition activity and the adsorption mechanisms.更多还原
