In the present study, for the first time, photodegradation of lindane compared with adsorption technique in water environment using synthesized TiO2-NPs was investigated. Some effective parameters for lindane removal by photocatalyst were systematically optimized. The mechanism of lindane removal using TiO2-NPs is also suggested on the basis of degradation kinetic and the change in surface charge.
