Abstract

Peculiarities of the sorption of methanal on a polyfunctional anion exchanger are investigated. Based on the sorption isotherm, it is established that the distribution coefficient of the aldehyde in the ion exchanger-solution system depends exponentially on the concentration of the external solution. From breakthrough curves of sorption, the rate-determining stage of the absorption of the aldehyde in dynamic conditions is estimated. Structural changes in the sorbent phase saturated with methanal are supported by IR spectroscopy.
