Combined with ultraviolet radiation as an accessory factor, ozone can result in accelerated degradation of chitosan. The ultraviolet radiation-induced accelerated degradation of chitosan was demonstrated by means of determination of viscosity-average molecular weight (Mv). In addition, the structure of the degraded chitosan obtained by ozone treatment combined with ultraviolet radiation was characterized...
Under conditions of continuous ozone gas application and constant ultrasonic radiation (UR), chitosan was effectively degraded. The existence of a synergetic effect of ozone and ultrasonic radiation on the degradation of chitosan was demonstrated by means of determination of viscosity-average molecular weight. The efficiency of the ozone and ultrasonic radiation treatment compared with acid hydrolysis...
