Abstract: The current paper presents a novel Pb(II) ion-imprinted silica-supported organic-inorganic hybrid sorbent functionalized with chelating S,N-donor atoms by coupling a surface imprinting technique with a sol-gel process for the selective adsorption of Pb(II) ions from aqueous solution. Fourier transmission infrared spectroscopy, scanning electron microscopy, and N2 adsorption-desorption isotherms were used to characterize the Pb(II)-imprinted hybrid sorbent. The results revealed that the Pb(II)-imprinted hybrid sorbent had high adsorption capacity (54.9 mg g-1), fast adsorption equilibrium rate within 30 min, wide pH range (3.5-6.5) for constant adsorption capacity, high selectivity, and good regeneration performance
