Abstract Share this page

The present investigation studies the use of powdered straw from Triticum aestivem for removal of lead (II) ions from its aqueous solution. Variation of contact time, biomass quantity, pH and temperature has been investigated as the major contributing factors. The sorption efficiency of the biomass has also been compared with that of cellulose, an adsorbent. At optimum conditions, the maximum removal of lead was observed to be 85% by dried biomass and 80% by cellulose for a 10 mg L ' solution of lead (II) ions. The sorption process obeyed a heterogeneous adsorptin model (Freundlich Isotherm) rather than a monolayer one (Langmuir Isotherm). Release of H+ ions during process showed an ionexchange mechanism for metal removal by Tritcum aestivum.
