Removal of Heavy Metals and Dyes Using Low Cost Adsorbents from Aqueous Medium-, A Review

Abstract

The removal of heavy metals and dyes from waste water using low cost adsorbents is being widely used by various researchers. In recent years, the uses of various natural adsorbents have been widely used as a replacement for the current costly methods of treatment of waste water. In this review, an extensive list of recent investigations and literature has been compiled to provide information on a wide range of low cost adsorbents.
