Abstract
The photocatalytic method was proposed for the destruction of expired medicinal products and medical waste. The use of this method was investigated towards the reaction of photocatalytic degradation of antibiotic rifampicinum in water solutions. Unmodified mesoporous anatase and rutile and modified with C3N4 were used as photocatalysts. All powders were synthesized by thermal hydrolysis of TiCl4 solutions. The modified anatase and rutile were produced by calcination with various amounts of melamine in the inert atmosphere. X-ray powder diffraction, scanning electron microscopy, Brunauer-Emmett-Teller surface area analysis were used to characterize the powders. It was established that only 19.8% of rifampicinum was destroyed under UV irradiation during 90 min. The percentage of degradation increases by 2.5 times in the presence of unmodified anatase and rutile and by 3.5 and 4 times in the presence of the modified samples, respectively.
