Abstract

Chitosan-zinc complexes with different zinc content were prepared electrochemically, monitored by
atomic mass spectrophotometer and characterized by FT-IR, XRD, UV and TEM. It was found that the
complexes with different zinc content showed different molecular structures. Molar ratios of chitosan
zinc complexes were formed depending on the duration time of electroxidation process. Complexes
have been partial random crystalline, while maximum concentrated complexes exhibited complete
ordered amorphous. UV radiation reduction has been used to produce chitosan zinc nanocomposite.
Zinc and zinc oxide nanoparticles have been detected. The colloidal solution has been found extremely
stable for more than six months at ambient atmosphere.
