Sažetak
Solar photocatalysis has been proven as a promising technology for air purification for real scale applications. One of the most researched photocatalysts, titanium dioxide (TiO2) irradiated with UV light, can decompose many organic compounds to water, carbon dioxide, and mineral acids or their salts Nowadays, a variety of reactors and methods of photocatalyst immobilization have been proposed for air treatment. Rubber tiles as an existing product from recycled rubber (floor covering and cast rubber) were immobilized with commercially available TiO2 P25 by sol-gel method in order to get photocatalytic active layer on the product surface. The photocatalytic wind tunnel is a custom-made reactor designed by the principles of a wind tunnel with the blower. The whole construction was adjusted to the test chamber in order to achieve simulation of an outdoor environment. Therefore, in this work, we are presenting photocatalytic wind tunnel (PWT) as the reactor for testing photocatalytic degradation of airborne pollutants by TiO2-immobilized on rubber tiles. Immobilization was validated by SEM-EDS and FTIR analysis. The stability and environmental impact of PRT were investigated by leaching test and AAS and TOC analyses. The results of the leaching test are compared with the Ordinance on the methods and conditions for the landfill of waste, categories, and operational requirements for landfills and the Toxicity Characteristic Leaching Procedure (TCLP).
