Novel ternary nanocomposite (TiO@FeO-chitosan) system for nitrate removal from water: an adsorption cum photocatalytic approach.

Nitrate pollution of water emerging from various anthropogenic activities has become a major environmental concern because of its deleterious effects on natural water resources. The present work deals with the synthesis of the ternary nanocomposite based on chitosan, iron oxide (FeO), and titanium dioxide (TiO) and its application for the removal of nitrates from model-contaminated water. FeO derived through a coprecipitation method was incorporated into the chitosan matrix which was fabricated in the form of beads.
