A Review on Removal of Dyes from Aqueous Solution by Various Adsorbents

The quality of water resources is declining due to urbanization, unsustainability practices, industrialization and pollution. Various dyes and metal ions cause contamination of water bodies. Dyes are released from leather, pigment and textile industries. They alter the colour, taste and odour of water, decreases oxygen concentration, endangering aquatic life and cause serious health issues in humans. Among the effluent treatment technologies adsorption is considered as efficacious and reliable. In this review paper a list of literature has been compiled with regard to various adsorbents used for the removal of dyes from wastewater.
