Effect of Soil Kinds,Temperature and pH on Adsorption for Norfloxacin in Soil

Yan Wang

Abstract

Static experiments for adsorption behavior of norfloxacin in soils were carried out to investigate the influence of temperature and pH on adsorption.The results indicated that the adsorption isotherms of norfloxacin in three kinds of soils were well described by the Freundlich type.Adsorption constant of organic mater of norfloxacin averaged 14.475,and the free energies of norfloxacin adsorption were-7.549～-5.284 kJ·mol-1 at 303.15 K.
