Abstract
This paper studied the tetracycline adsorption behavior on Magnetic ion exchange resin by static experiments.The influence of different pH and tetracycline initial concentration on adsorption effect were investigated,adsorption isothermal models and kinetics were analyzed,and adsorption mechanism were illustrated.The result showed that Magnetic ion exchange resin has good adsorption effect for tetracycline.The kinetic studies indicated that the adsorption of tetracycline onto Magnetic ion exchange resin well described with pseudo-second-order kinetic model.Adsorption isotherm experiments suggested that Freundlich model is better than Langmuir model to describe the Magnetic ion exchange resin adsorption process of tetracycline.The D-R model showed that the process was mainly dominated by the ion exchange.The adsorbing effect of tetracycline under the neutral and acid condition is better.The adsorption of tetracycline on Magnetic ion exchange resin was spontaneous,endothermic and entropy increase process,the increase of temperature did benefit to the adsorption process.关键词
