AN51: Method for Determination of Anions in Sodium Hydroxide Be the first to rate this application

anions sodium hydroxide

Description

Caustic manufacturers need an accurate method to monitor the concentration of chlorate and other anions in their chlor-alkali processes. In chlor-alkali processes, chlorine and sodium hydroxide are produced by the electrolysis of a saturated brine solution. Monitoring the chlorate concentration ensures the process is working correctly. This method is used to determine the levels of anionic impurities in a 50% sodium hydroxide solution. Anions which can be determined by this method include chloride, nitrite, sulfate, phosphate, chlorate, and nitrate.
