Özet:

Today, organic anti-microbic substances have increased the concern due to their potential health effects on human and natural life. Triclosan (TCS) is the commonly known as anti-bacterial or anti-microbic and cleaning products. There is strong evidence that water plants and other aquatic species are more sensitive to triclosan. New products are resulting from the decomposition of triclosan, which easily founded at the effluent of wastewater treatment plants. TCS is a kind of an endocrine distractive chemical and gives damage to the aquatic eco-system and human health in the long term. The purpose of this study was to investigate the elimination of TCS from wastewater by using the photo-oxidation method. The removal of TCS studied using ultraviolet light and newly developed catalysts. The Poly(dimethylsiloxane) (PDMS) modified Nafion/Silica composite catalyst was successfully destroyed the TCS to the sucrose without any iron sludge production. In addition, it is possible to re-use the catalyst several times with negligible iron leaching amounts. Consequently, PDMS modified catalyst was successfully applied to destroyed TCS in 60 min. of exposure time with using only 34 mg/L H2O2 and 0.1g of catalyst.
