Use of chemically modified chitosan beads for sorption and enzyme immobilization
TLDR
In this paper, it was shown that the degree of cross-linking could be well described by the Freundlich equation and the amounts of sorption of solutes and the immobilization capacities of enzymes onto the swollen chitosan beads were significantly affected by the degrees of crosslinking.About:
