Abstract

The purpose of this work was to examine the photocatalytic activity of Chitosan/Zn- gel blend film. It is well known that Chitosan can do photo-degradation; Zinc gel was added as a blend to enhance the photo-catalytic behavior of chitosan. Their photocatalytic activities were estimated by the degradation of the used dye from its solution by using the Chitosan/Zn-gel blend film. The influence of operating parameters such as Zn-gel concentration was thoroughly examined to obtain the optimum conditions for photo-catalytic degradation. The particle size for Zn-gel and the dielectric properties for Chitosan/Zn-gel blend was measured. The kinetics and color photo-degradation efficiency has been calculated based on spectrophotometry. It is found that the prepared blinds are very efficient as photo-catalytic media for the Methyl Orang; the color removal efficiency reached 87% which is great, especially since no complicated preparation followed and also no special irradiation only the sunlight The ε' and ε'' were measured in a frequency range extending from 1 Hz up to 100 kHz. The frequency enhancement results in collapsing of the ε' amounts for all mentioned prepared samples and the ε' appeared independent of frequency.
