Recovery of [CO2]T from Aqueous Bicarbonate using a Gas Permeable Membrane

Abstract

Celgard 2400 gas permeable membranes were in contact with a model sodium bicarbonate solution on a closed system at elevated water pressures. When gaseous carbon dioxide was removed from the water by diffusion through the membrane, the bicarbonate disproportionated to carbon dioxide and carbonate. The carbon dioxide permeance rate and effect of ionic strength on disproportionation is reported.
