Chitosan was cross-linked to various extents with nitrilotriacetic acid in the presence of a water-soluble carbodiimide in homogeneous solution, and was then fully N-acetylated. The structure of the nitrilotriacetic acid residues attached to the chitin backbone was determined by acid-base titration.
Chitosan gel beads were prepared using an in-liquid curing method by the ionotropic crosslinking with sodium tripolyphosphate. Crosslinking characteristics of the chitosan-TPP beads were improved by the modification of in-liquid curing mechanism of the beads in TPP solution. Chitosan gel beads cured
