Abstract

Regarding issues like increase in world population, industrialization, global warming, and irregular consuming of the underground water sources led to less accessibility of clean water for daily needs and drinking. On the other hand, these less available water sources are exposing to hazardous and harmful pollutants like heavy metal ions. Therefore, purification of water sources became a huge concern. Many efforts have been made in this regard using numerous methods and materials. Some of them are expensive, complicated, and time-consuming. One of these materials, which are less expensive and simple, is metal oxides and their nanocomposite with polymers. Metal oxides owing to enormous capacity, high energy density, and rich resources are widely used and favorable, while metal oxides have some intrinsic defects like poor electrical conductivity, aggregation, and large volume change. A highly efficient to overcome these lacks is combining metal oxides with polymers to make polymeric nanocomposites. In this chapter, an endeavor has been made to demonstrate the superiority of metal oxides over other materials in water treatment as well as cover recent works based on the preparation of metal oxides and polymer/metal oxide nanocomposites and their capability in water treatment.
