✦ Synopsis

This paper discusses the interaction between chitosan and the polyphenols separated from spruce wood bark. The chitosan and the polyphenols formed a complex and the release of the polyphenols occurred only in an alkaline medium (pH . 9) in a two-step process. Analysis of the release of the polyphenols showed that in the initial stage the diffusion occurs according to the Fick's law, while in the last stage, the process develops according to a zero-order kinetics.
