| Abstract: | In order to apply the membrane electrolysis to the process of purging the low concentration SO_2 gas by the alkali-natrium method,we studied the relation between the electrolytic voltage and pH value of the electrolyte with the change of time during electolysis,the effect of acid cell temperature on the current efficiency and electrolytic voltage etc,as well as the effect of ratio of acid and alkali on the electrolysis effectiveness.The rational process flow was also proposed. |
