The blend membranes were satisfactorily prepared by coagulating a mixture of O-carboxymethylated chitosan (CM-chitosan) and alginate in aqueous solution with 5 wt % CaCl 2 , and then by treating with 1 wt % HCl aqueous solution. Their structure and miscibility were characterized by scanning electron
## Abstract Microporous cellulose membranes were prepared from novel cellulose/aqueous sodium hydroxide solutions by coagulation with aqueous H~2~SO~4~ solutions. The free and glassβcontacting surface morphology of the microporous cellulose membranes showed an asymmetric porous structure. The morph
