Chelation ion-exchange properties of copolymers prepared from salicylic acid, urea and formaldehyde by condensation in presence of acid catalyst were studied for Cu2+, Fe3+, UO2+, Mn2+,Zn2+ and Co2+ ions. A batch equilibration method was adopted to study the selectivity of metal ion uptake. This method involved the measurement of distribution of a given metal between the copolymer sample and a solution containing the metal ions. The study was carried out over a wide pH range and in media of various ionic strengths. The copolymer showed a higher selectivity for UO22+, Cu2+ and Fe3+ ions than Mn2+, Co2+ and Zn2+ ions.

Polymers were prepared by the condensation of 2, 4-dihydroxybenzaldehydeoxime (2, 4-DBO) and formaldehyde (F) in the presence of oxalic acid as catalyst with varying molar ratios of reacting monomers. Polymers were characterized by their IR spectra, elemental analyses, TGA and Mn as determined by vapour pressure osmometry as well as by non-aqueous conductometric titrations. Viscosity measurements of the solutions of polymer samples were carried out in dimethylformamide. Chelation ion-exchange properties have also been studied employing the batch equilibration method. This method involved the measurement of distribution of a given metal between the polymer sample and a solution containing metal ions. The study was carried out over a wide pH range and in media of various ionic strengths. The polymer showed a higher selectivity for UO22+ and Fe3+ ions than for Cu2+, Ni2+, Co2+ and Mn2+ ions.

Solid complexes of a-oximinoacetoacetanilide thiosemicarbazone (OAATS) with Ni(II), Co(II), Zn(II), Mn(II), Cd(II), Hg(II) and UO2(II) have been prepared and characterized on the basis of their elemental analyses, conductivity, differential scanning calorimetry, thermogravimetric analysis, infrared and electronic spectral measurements, in conjunction with magnetic susceptibility measurements. Molecular orbital calculations employing the CNDO/2 method have been made for a number of conformations of the ligand molecule to ascertain the most stable one.
