Polypropylene fiber grafted calcium alginate with mesoporous silica for adsorption of Bisphenol A and Pb.

Polypropylene grafted calcium alginate with mesoporous silica (PP-g-CaAlg@SiO) for adsorbing Bisphenol A (BPA) and Pb was prepared by calcium chloride (CaCl) crosslinking and hydrochloric acid solution treatment. The PP-g-CaAlg@SiO was characterized by SEM, TEM, BET, XRD, FTIR and TG. PP-g-CaAlg@SiO exhibited excellent adsorption capacity for BPA and Pb, because the formation of reticulated nanorod structure increased its specific surface area.
