Abstract
PURPOSE: To introduce CO2 gas, etc. into 15π or more NaOH solution containing impurities ( esp. chlorine) produced by a diaphragm process and to from and separate crystals at a specific pH value so as to purify the NaOH solution up to the quality close to that of NaOH obtained by a mercury process.
