Abstract

Formaldehyde reacts with bisulfite to form hydroxymethanesulfonate, which is a conjugate base of a strong acid, and is able to be transported actively by the coupled countertransport of hydroxide ion through an anion-exchange membrane. The permeation rate is controlled by pH and formaldehyde can be separated readily from other types of organic solutes via this method.
