Rice husk is a low value agriculture by-product abundantly available in India. In recent years, it has been widely investigated as a biosorbent for removal of heavy metals such as Au, Cd(II), Cr(VI), Cu(II), Ni(II), Pb(II), Zn(II) etc. from water and waste water. An extensive list of previous and current literature on rice husk in removing heavy metals has been compiled to provide a summary of available information on rice husk and its potential as a low cost biosorbent.
