Preparation of cross-linked m.gnetic chitosan with quaternary am.onium.and its application for cr(Ⅵ) and P(Ⅴ) rem.val

Pollutants that exist in anionic species are issues of concern in water treatm.nt. com.ared to cationic pollutants, the rem.val of anionic pollutants by adsorption is m.re difficult because m.st adsorbents carry predom.nantly negative charges in neutral and alkaline environm.nts. In this study, a cross-linked chitosan derivative with quaternary am.onium.and m.gnetic properties（Qm.chitosan） was prepared and em.loyed to rem.ve chrom.um.VI） and phosphorus（V）（cr（VI） and P（V）） from.aqueous environm.nts. The Qm.chitosan was characterized by Fourier transform.infrared spectrom.try（FT-IR）,therm.gravim.tric analysis（TGA）, energy dispersive X-ray（SEm.EDX） and zeta *** experim.nts show that Qm.chitosan can effectively rem.ve cr（VI） and P（V）, and the m.in m.chanism.was believed to be electrostatic interaction. A pseudosecond-order m.del was fitted to describe the kinetic processes of cr（VI） and P（V） rem.val. The adsorption isotherm. of both cr（VI） and P（V） on the Qm.chitosan were well fitted by the Langm.ir isotherm.equation. The saturated adsorption capacity of P（V）（2.783 m.ol/g） was found to be higher than that of cr（VI）（2.323 m.ol/g）, resulting from.the size of the H2PO-4ions being sm.ller than that of the Hcr O-4ions. However, the theoretical calculation and experim.ntal results showed that Qm.chitosan had a stronger affinity for cr（VI） than P（V）. The adsorption–desorption of the Qm.chitosan was evaluated, and high regeneration rates were dem.nstrated.
