| Tartalmi kivonat: | Among the increasing water pollution, organic dyes have gained growing attention because their environmental persistence and resistance to conventional treatment technologies. The widespread use of organic dyes in textile industry produced a great damage to the ecoenvironment. There are many different organic textile dyes in synthetic-cotton textile industries, for instance, reactive azo dyes or triaryl methane-based dyes, which are known to have carcinogen and mutagenic effects. The aim of our research is to resolve the problems caused by the textile industries using TiO2-WO3 composite photocatalysts. The most efficient composite was characterized by SEM, DRS and XRD and its photocatalytic activity was investigated in-detail. The reusability of the composite was also investigated showing the increased photostability of these materials. The composition of the composite and the most preferable operational pH value was optimized in order to further enhance the efficiency of the composites. |
