摘　　要：在研究锌锰干电池缓蚀剂的基础上 ,筛选出了缓蚀效果较好的植酸盐缓蚀剂 .实验结果表明 ,植酸盐的最佳质量分数为 0 .0 1 % .用循环伏安仪和交流阻抗进一步对其缓蚀机理进行了研究 ,得出植酸盐的缓蚀机理为化学吸附过程 .The selected inhibitor of plant acid salt has a higher inhibiting efficiency on the basis of the study of inhibitor in zinc-manganese battery. The experimental results show that the inhibiting effect is the best when its mass fraction is 0.01%. The inhibiting mechanism was studied by measuring cyclic voltammogram and the circuit impedance curves. The result shows that the inhibiting mechanism of plant acid salt is a chemical adsorption process.
