Adsorption techniques are widely used to remove certain classes of pollutants from waters, especially those which are not easily biodegradable. Currently a combination of biological treatment and adsorption on activated carbon is becoming common for removal of dyes from waste water. There are plenty of evidences for removal of pollutants using granular activated carbon as an adsorbent contrary to the fact that even bioadsorbent could serve the purpose, as such alternative non-conventional eco friendly sorbents have been investigated. It is well known that natural materials, waste materials from industry and agriculture waste can be obtained and employed as inexpensive sorbents. In present study an extensive list of sorbent literature has been complied which presents a critical analysis of these materials describes their characteristics, advantages and limitations. In particular, nilgiri bark might be promising adsorbent for environment and its purification purpose.
