Abstract
The application of new nanocomposites SiO2-TiO2-MWCNT and SiO2-TiO2 obtained by sol-gel method was investigated in the removal of diclofenac (DCF) from water under illumination centered at 365Â nm and 550Â nm. The investigated nanocomposites enabled to remove DCF almost completely after 60Â min of treatment. The mechanism of the photocatalytic removal of DCF under irradiation of 365Â nm and 550Â nm seems to be similar. The process followed pseudo-first order kinetics and the highest k1 was noted for nanocomposites treated in acidic conditions (13.65.903Â ÃÂ 10â2Â minâ1). Microtox® test revealed decreased toxicity of treated water.
