Abstract
Separability of SO2 from mixtures of SO2 and N2 gases was studied for membranes of poly (vinyl alcohol) (PVA) and cellulose modified with me thyl, ethyl, t-butyl, and phenyl vinyl sulfoxides. Of these sulfoxide- modified polymers, the phenyl vinyl sulfoxide-modified PVA membranes w ere found to give the best separation of SO2. In the phenyl vinyl sulf oxide-modified PVA membranes, the permeability coefficient of SO2 incr eased with sulfoxide content while separability of SO2 was maximum at a sulfoxide content of 23.5 mol %; the separation factor of SO2 was ab out 170 at this sulfoxide content.
