  • Abstract

    Three new chelating resins o-hydroxybenzaldehyde-2-aminothiazole-formaldehyde (o-HB-AT-HCHO), o-hydroxybenzaldehyde-6-methyl-2-aminobenzothiazole-formaldehyde (o-HB-MABT-HCHO) and o-hydroxybenzaldehyde-6-chloro-2-aminobenzothiazole-formaldehyde (o-HB-CABT-HCHO) having heterocyclic ring systems and multiple functional groups were synthesized by condensing the Schiff bases of o-hydroxybenzaldehyde-2-aminothiazole (o-HB-AT), o-hydroxy-benzaldehyde-2-amino-6-methylbenzothiazole (o-HB-MABT) and o-hydroxybenzaldehyde-2-amino-6-chlorobenzothiazole (o-HB-CABT) with formaldehyde. Their metal polychelate with Cu2+, Ni2+, Fe3+ and UO22+ were prepared. The Schiff bases, resins and polychelates were characterized by various instrumental techniques like FTIR, 1H NMR, TGA and DSC studies. These spectral and thermal studies provide very valuable information about the structural features, stability and crystallinity of the Schiff bases, resins and polychelates
