Abstract

Today purification of water is essential and to fulfil the water demand of the growing population and shrinking water resources. In last decades due to industrialization and overpopulation, the water quality is been degraded not only of surface water but also of groundwater because of constant release of industrial effluent directly to the water bodies without any primary treatment and over exploitation on groundwater. Among several water treatment technology adsorption is mostly considered one that is easy to manage, demand less cost and energy. However, synthesis of an effective environmentally benign and economically sustainable adsorbent is the centre of focus of researchers these days. There are various adsorbents like nanoparticles, activated carbon and zeolite etc. are being used yet for the removal of various water pollutants. In this chapter, the adsorbents are divided into natural, carbonaceous and nanoparticles categories and their various uses in water treatment are described.
