  • Title: Preparation and analytical properties of a chelating resin functionalized with 1-hydrazinophthalazine ligand.
    Author: Pathak R, Rao GN.
    Journal: Talanta; 1997 Aug; 44(8):1447-53. PubMed ID: 18966882.
    Abstract:
    A poly[styrene-co-(divinylbenzene)] resin (XAD-4) functionalized with 1-hydrazinophthalazine ligand has been prepared and its analytical properties investigated. The pH dependence of sorption of metal ion on the resin has been determined for Cu(II), Ni(II), Co(II), Zn(II), Cd(II), Pb(II), Fe(III) and Cr(III). Trace amounts of these metal ions were quantitatively retained on the resin and recovered by eluting with 1 mol l(-1) hydrochloric acid. The resin was found to be selective for Fe(III) and its separation from other metal ions was carried out effectively. Metal ions concentrations were determined using AAS.
