摘　　要：测量了21种有机表面活性剂在锌粉表面的析氢速度,从中选出8种抑制析氢能力较强的缓蚀剂,并通过测量锌电极在铵型和锌型电解液中的阴、阳极极化曲线来考查缓蚀剂对锌电极电性能的影响.结果表明,本文所选的缓蚀剂CNB-16既具有明显的抑制析氢的能力,又不会严重影响锌在电解液中的阳极溶解.因此,认为CNB-16有希望成为Zn-Mn干电池中取代汞的无毒有机缓蚀剂.We have measured the rate of gas evolution from the zinc surface added 21 kinds of organic surfactants separately, but only 8 kinds are of proved successful. The polarization of zinc electrodes have been tested in solutions contained the additives. The experiments show that among the surface activators tested,CNB-16 is more effective in reducing hydrogen gassing without impeding anodic reaction of zinc. Therefore, We think CNB-16 is promising to be a substitute for mercury in zinc-manganese dry cells.
