Novel nickel-functionalized glycoboehmite materials for iodide and arsenate capture.

ABSTRACT: Selective adsorption of anions from aqueous solutions is essential to many industrial and remediation applications. A novel anion sorbent was developed using hybrid glycoboehmite (GB) synthesized from 1,4-butanediol and potassium hydroxide mineralizer. GB materials were further functionalized through Ni²⁺ adsorption from aqueous solutions. The adsorption capacity of GB for Ni²⁺ was found to be 2 to 5 times greater than that for Mg²⁺ or Ca²⁺, and 12 times higher than that of simple boehmite normalized to the surface area. Relative to GB, nickel-functionalized GB (Ni-GB) exhibits favorable adsorption properties for arsenate and iodide with much improved partitioning coefficient values (K_D) of ~ 6400 and 43 mL/g respectively.
