摘　　要：主要讨论海水温度的变化对海水电解用阳极过程的影响。温度升高,析氯电位和阳极电极电位降低,有利于氯气的析出。但同时温度升高,氯气在海水中的溶解度降低,次氯酸盐的分解加剧,从而导致阳极电流效率下降,电解的直流电耗上升。The influence of temperature on the anodic process of seawater electrolysis are discussed. The potential of chlorine evolution and anodic potential decrease with the temperature increasing, and it is beneficial to chlorine evolution. On the other hand, with the increasing of temperature, the solubility of chlorine decreases and the decomposition of hyperhlorite accelerates, so the current efficiency decreases and the specific DC consumption increases.
