摘要：

Novel chitosan-ZnO complexes are prepared using zinc chloride, sodium hydroxide and chitin as source materials by direct precipitation method. Four chitosan-ZnO complexes are prepared for different concentrations of source material. The chitosan-ZnO complex formations have been confirmed by FTIR spectroscopic analysis. Hexagonal structure and crystalline size (35-51 nm) of zinc oxide are determined by XRD. Rod-like particle shape of chitosan-ZnO complex from SEM images, higher UV rays absorption in the region of 200-275 nm by UV-vis and higher UV emission at 422 nm by photoluminescence spectrophotometer are recorded. The rod-like chitosan-zinc oxide was obtained with optimum concentration of 45% NaOH and 15% ZnCl2. The size of the complex was increased with increase of sodium hydroxide concentration.
