REMOVAL OF LINDANE AND DIELDRIN FROM AQUEOUS SOLUTIONS BY MONTMORILLONITE AND BENTONITE AND OPTIMIZATION OF PARAMETERS
(PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2009) Aydin, Mehmet E.; Ozcan, Senar; Beduk, Fatma
Different pesticides are widely applied in agricultural activities. To remove these toxic compounds from the aquatic environment and to reduce the dispersion of pollutants, different clays can effectively be used as alternative adsorbents to commonly used activated carbon. In this study montmorillonite and bentonite clays were used to adsorb lindane (gamma-HCH) and dieldrin, by a batch equilibration technique. The study was carried out as functions of contact time, pH, initial lindane and dieldrin concentrations, amount of montmorillonite and bentonite and adsorption isotherms were obtained as Freundlich Isotherm. Clays were activated by calcination and acid treatment. Adsorption was improved after acid treatment of used clays, however calcinations of the clays up to 500 degrees C did not reveal any discernible effect on the adsorption.
