SYNTHESIS, CHARACTERIZATION, AND APPLICATIONS OF POLY(SALICYLALDEHYDE-ACRYLATE-DIVINYLBENZENE) OXIME AS A CHELATE POLYMER TO NI(II), CO(II), AND CU(II) IONS

A three-dimensional polymer backbone was prepared from salicylaldehyde-acrylate monomer using benzoyl peroxide as the catalyst at 80 +/- 0.2 degrees C by the suspension polymerization technique. Through a postpolymerization reaction, a chelating group, oxime, was attached to the aldehydic functional group. The oximated resin was treated with Ni(II), Co(II) and Cu(II) ions. The parent polymer, functionalized polymer, and its Ni(II), Co(II), and Cu(II) metal chelates were characterized by IR, H-1-, C-13-CP/MAS NMR, EPR, TG-DTA, magnetic studies, and optical and SEM microphotographs. The maximum capacity of the resins for the metal ions and the recyclability of the resins were established. The physical aspects of the beads are discussed through optical and SEM photographs.
