In article [1], a comparison of photocatalytic activity of crude TiO2 and TiO2 immobilized on activated carbon particles are presented. These samples were analyzed for the degradation of pharmaceuticals: paracetamol, amoxicillin, diclofenac, and ampicillin. The oxidation of drugs took place with the help of solar radiation. The composite TiO2 immobilized on the surface of carbon was obtained by temperature impregnation. TiO2 particles have been successfully immobilized on activated carbon. This is shown by the results of the BrunauerEmmett-Teller analysis, scanning electron microscope and Fourier transforms infrared spectroscopy. The TiO2 composite is completely dissolved ampicillin and amoxicillin. Pure TiO2 expanded these drugs by only 83 % and 89 % respectively. The composite has achieved a higher degree of removal of paracetamol (70 %) and diclofenac (85 %) than pure titanium oxide. It has been found that the composite TiO2 has lower costs of full scale solar photocatalytic reactor.
