摘要:
A method for controlling chlorates in an aqueous alkali metal hydroxide liquor produced by an ion exchange membrane electrolysis is provided, which comprises adding a reducing agent to brine to keep the concentration of chlorates to a specified value or less. The present invention provides an alkali metal hydroxide liquor with low content of chlorates.
