CROSS-LINKING OF CHITOSAN WITH GLUTARALDEHYDE IN THE PRESENCE OF CITRIC ACID——A NEW GELLING SYSTEM*

Received Date: 10 September 1998

The procedure for preparing a new type of uniform and porous chitosan gel from citric acidmedium is described. Its swelling behavior in different media was compared with those of the gels preparedby other methods. The ultrastructure of the xerogel prepared from citric acid was characterized using electronmicroscopy (SEM).
