Synthesis composite of TiO2/chitosan and TiO2/ bentonite for removing turbidity from Ismailia Canal as water treatment plant

Abstract

The conditions of water in Ismailia canal (Mostorod refinery site) are alarming now because it looks more cloudy and dirty. Water was contaminated not only organic trashes, but also inorganic. The adsorption capacity of clays is often used to remove undesirable substances from aqueous solutions. Chitosan is widely used in biological applications due to its biocompatibility and biodegradability. The aim of the present study is to review the possible applications of the nanotechnology for the removal of pollutants from wastewater by TiO₂/Bentonite and TiO₂/Chitosan, when added this composite to wastewater and when exposed to visible light they will generate OH radical compounds that can degrade organic pollutants and compounds superoxide, at pH 2.
