Abstract
In this study, samples of fine-grained concrete with the additive T1O2 microparticles were made. The photocatalytic properties of TiO2 for the decomposition of anthracene in solutions under UV irradiation were studied. To evaluate the efficiency of photodegradation, the method of luminescence analysis was used. For improving the quality of the analyzed solutions, model surfaces were made based on chitosan with the addition of TiO2. According to the results of the experiments, it was found that the degree of photodegradation of anthracene in solutions using solid chitosan-TiO2 matrices reaches 74% after 60 minutes under UV irradiation. The conducted studies confirm the feasibility of using chitosan-TiO2 matrices as model surfaces for studying the photocatalytic properties of TiO2 for the oxidation of anthracene.
