Abstract

A novel organic-inorganic hybrid fiber (Pb(II)-IIPs) which can selectively adsorb Pb(II) was prepared by surface imprinting technology. Mesoporous silica was grafted onto polypropylene fibers (PP) and used as the substrates. To achieve high selectivity, Pb(II)-IIPs was synthesized employing functioned iminodiacetic acid (IDA) as a functional ligand, coordinated with Pb(II), followed by cross-linking with glutaraldehyde to stabilize the imprinting cavities. The selectivity coefficient values (k) of Pb(II) -IIPs for Pb(II)/Cd(II), Pb(II)/Co(II), Pb(II)/Ni(II), Pb(II)/Zn(II) are 7.78, 220, 132, and 45.6, respectively. The maximum theoretical adsorption of Pb(II)-IIPs is 114.03 mg g⁻¹, with equilibrium achieved in 60 min. After five cycles, the adsorption remained above 80 %. The high adsorption capacity and selectivity of Pb(II)-IIPs demonstrate promising potential for remediating Pb(II)-contaminated groundwater systems, particularly in selective recovery of Pb(II).
