Preparation of magnetic separable CoFe2O4 PAC composite and the adsorption of bisphenol A from aqueous solution

الملخص EN

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.-
