Abstract:
Terpolymer MAF synthesized by the polycondensation of melamine (M) and aniline (A) with formaldehyde (F) in the presence of an acid catalyst in 1:1:3 molar proportions of the reacting monomers. Polychelates were prepared by using metal acetate, metal salts and MAF ligand in DMF medium. The prepared terpolymer and its polychelates were characterized by using elemental analysis, magnetic studies and spectral analysis. In the present paper, electrical conductivity properties of the terpolymer and its polychelates were studied over a wide range of temperature and is in the order MAF <Mn(II)<

All polychelates are coloured, amorphous solid insoluble in water and common organic solvents and characterized with the aid of analytical, magnetic, spectral and thermal studies. The Mn(II),Co(II) and Ni(II) polychelates are of a six co-ordinated octahedral structure, where as Zn(II) and Cd(II) polychelates are found to be four co-ordinated while Cu(II) exhibit square planer structure respectively.

Abstract:
Preconcentration of Cu (II) from seawater using a novel phenol–formaldehyde (P–F) resin was investigated. 1,2-dihydroxybenzene-4-azo-3-hydroxybenzene-formaldehyde resin (DAHBF) was prepared by condensing 1,2-dihydroxybenzene-4-azo-3-hydroxybenzene with formaldehyde (1:2 mole ratio) in the presence of oxalic acid as catalyst. Polychelates were obtained when the DAHBF was treated with the aqueous solution of Cu (II) ions. The polymeric resin and polymer-metal complexes were characterized with thermal analysis and spectral studies. The IR spectra of polychelates suggest that the metal was coordin
