Abstract

The article considers the effect of modification of commercial material P25-TiO2 with yttrium oxide and the effect of the modifier nature on the photocatalytic activity towards ciprofloxacin. TiO2 modification with yttrium oxide enhances the degree of antibiotic degradation. Increase in modifier content affects the photoactivity of TiO2 ambiguously: when yttrium chloride is used as a precursor, photoactivity increases; when yttrium nitrate is used – photoactivity decreases. Additional use of an oxidant (H2O2) significantly increases (more than 2 times) efficiency of the photocatalytic process. It has been found that at low concentrations of antibiotic aqueous solution (up to $10\ \mathrm{mg/dm^{3}}$), its photodegradation over TiO2 modified with yttrium oxide reaches 100%. However, in case of high concentrations of ciprofloxacin (up to $50\ \mathrm{mg/dm^{3}}$), complete degradation of the antibiotic is observed only when the combination of TiO2 modified with yttrium oxide and oxidant H2O2 is utilized in the photocatalytic process.

氧化钇修饰P25-TiO2对环丙沙星的光催化活性

本文研究了用氧化钇对商品材料P25-TiO2进行改性的效果，以及改性剂性质对其对环丙沙星光催化活性的影响。用氧化钇修饰TiO2提高了抗生素的降解程度。改性剂含量的增加对TiO2光活性的影响是模糊的:当使用氯化钇作为前体时，光活性增加;当使用硝酸钇时，光活性降低。额外使用氧化剂(H2O2)可显著提高光催化过程的效率(超过2倍)。研究发现，在低浓度的抗生素水溶液中(高达$10\ \ mathm {mg/dm^{3}}$)，其在氧化钇修饰的TiO2上的光降解达到100%。然而，在环丙沙星浓度较高的情况下(高达$50\ \ mathm {mg/dm^{3}}$)，只有在光催化过程中利用氧化钇修饰的TiO2与氧化剂H2O2的组合才能观察到抗生素的完全降解。
