Urea Permeability of Citric Acid Crosslinked Chitosan-Poly (Vinyl Alcohol) Blend Membranes

Lusiana R. A., Isdadiyanto S., Khabibi, Siswanta D., and Mudasir

Abstract—Chitosan-citric acid cross-linking reaction showed that group modification group was able to increase the number of carrier compound active groups which led to the increase of membrane transport capacity. Substitution of the carboxyl group was also shown to reduce the adsorption of proteins on the membrane surface. This was confirmed by SEM analysis of the surface both chitosan and CS.cl.CA after contact with albumin. CS.cl.CA membrane transport capacities for urea IS 287 mg/L, respectively. Vitamin B12 and albumin were not able to pass through the membrane as indicated by the absence of UV-Vis absorption of both compounds in the acceptor phase. The characterization using FTIR spectrometry showed that cross-linking reaction has occurred for chitosan.

Index Terms—Crosslinking, active groups, transport, membrane, adsorption.
