In the brine flowing in and out of the electrolyzer, the concentration of sodium chlorate (in total) in the brine leaving the electrolyzer is much higher than that in the brine entering it; the source of sodium chlorate is the discharge of hypochlorite ions； Chlorine reacts with sodium hydroxide; please discuss what the main source of the increased chlorate content in the brine exiting the reactor is, as well as the calculation methods used in material balance calculations. # ， ， &
The most direct reason is the change in the volume of the saltwater; Asahi Kasei generally requires a level of less than 5 g/l before it enters the tank, and less than 7 g/l after dechlorination； Then there are the side reactions at the anode, which are related to factors such as the amount of acid added, the operating time of the membrane, and the quality of the anode coating
