In the present paper the results regarding the influence of UV-irradiation with 254 nm wavelength
on the molecular weight of chitosan are presented. The concentration of chitosan solution was
0.5%(w/w) in 0.1 M acetic acid. The degree of deacetylation, determined by potentiometric
titration in an acidic solution by alkaline, was 81%. Viscosity-average molecular weight of
chitosan was determined using an Ubbelohde capillary viscometer. Mark–Houwink equation
for the calculation of molecular weight was applied. The results showed that the viscosityaverage
molecular weight of chitosan was decreasing with increasing time of exposure to
UV-irradiation. Spectroscopic analysis of UV-Vis and FTIR confirmed the photodegradation
processes of chitosan. The increasing absorbance in UV-Vis spectra indicated the formation of
new chromophoric groups after UV-irradiation of chitosan. Microscopic studies showed changes
on the surface of the irradiated films of chitosan and decrease of the surface roughness.
