1D Recyclable ASP-Fe₃O₄@PAM Composites As Bio-adsorbent For High-efficient Pb??? Removal From Water

Heavy metal pollution is one of the most serious environmental problems,posing threats to human health.Treatment of pulveralent adsorbents to add micro carrier that increase retrievability and sorption capacity is a feasible method to achieve its practical application.Here,we provided a simple solution method to loading recyclable Fe₃O₄@PAM on the surface of fungus and then prepared a novel one-dimensional?1D?Asp-Fe₃O₄@PAM composites.Then as-prepared composites were used to evaluate the removal of Pb?II?from water.Experiment results revealed that the sorption isotherms and the kinetic modeling were well fitted by the Freundlich sorption isotherms and pseudo-second-order.Moreover,the Asp-Fe₃O₄@PAM bio-adsorbents showed high biological activity,effectivity and synergy with high sorption capacity of 247.6 mg/g for Pb?II?ions within 20 minutes.In addition,the large size,easy separation properties and competitive adsorption tests demonstrated the obtained Asp-Fe₃O₄@PAM could serve as a potential candidate for removing heavy metal ions from the waste water.
