Preparation and characterization of a novel AMP/PAN nanofiber adsorbent by electrospinning method for adsorbing cesium metal ion from wastewater solution

Adsorption of Cs+ ion from aqueous solution onto a novel electrospun ammonium molybdophosphate(AMP) /polyacrylonitrile (PAN) nanofiber adsorbent was studied at 25 0C. The physicochemical characterization wasperformed by FTIR, BET and SEM analyses. The investigation showed the maximum adsorption capacity of 52.2 mg/gat pH 5, adsorbent concentration of 1 (g/L), 25oC and 100 (mg/L) initial concentration of Cs+ by AMP/PAN nanofiber.Also, the adsorption affinity of metal ions onto the adsorbent was in the order of Cs+> Co2+> Mg2+> Ca2+> Sr2+ thatshowed high selectivity of AMP/PAN nanofiber adsorbent for Cs+. The adsorbent can be easily regenerated after 5cycles of adsorption-desorption.
