Abstract

In this research, the ADSORPTION of some heavy and poisonous metal ions such as Hg2+, Pb2+, Cd2+ from aqueous solutions using ACTIVATED CARBON (ac.c), has been investigated. ACTIVATED CARBON employed was in the form of finely powdered form and the system was batch. In our preliminary investigation, it was found that powdered carbon is more effective than granule form in the ADSORPTION of these metal ions.Powdered ACTIVATED CARBONs have more sudace area and higher mass transport properties than granules.So it is more prefer for ADSORPTION of medium to high MW poisonous materials from water and waste waters. In this research, it was observed that with increasing the size of metal ions under investigation, the rate of ADSORPTION by ac.c increases too. Metal ions as simple and hydrated form have not much tendency for ADSORPTION by ac.c. However, with IMPREGNATION of ac.c.by some suitable chemicals, it is quite possible to increase the rate of ADSORPTION considerably. We also found that impregnated ac.c. With compounds that have sulfur atoms in their structure such as dithizone or methylene blue (a textile dye), considerable improvement in ADSORPTION of these dangerous HEAVY METAL IONS is achieved.
