Chelation of Chitosan and Its Derivatives on Soluble Vitamin

Chelation of Chitosan and its derivatives on soluble vitamin was investigated. Spectrophotometry was used to study the chelation of the chitosan,carboxymethyl chitosan on VB2 and VC under different pH,different times and different concentration,respectively. The result indicated that the effect of their chelation on was obvious. Moreover,concentration,pH and time all had different effects on the chelation.
