چکیده
|
Cofe2o4/pac composite adsorbent has been prepared via an immersing-calcination process,using ethylene diamine tetraacetic acid (edta) and citric acid (cit) ligands containing sol as the cofe2o4 precursor. the microstructure characterization and magnetic property of as-prepared sample were performed by means of xrd and vsm measurements. the adsorption kinetics,isotherms and thermodynamic process toward bisphenol a molecules (bpa,which is considered as one of the typical endocrine disrupting chemicals) occurred on as-prepared magnetic adsorbent which were investigated by the pseudo-second order kinetic/intraparticle models,the langmuir/freundlich adsorption isothermal models and basic chemical thermodynamics principles,respectively. © 2011.
