The resin was synthesized by condensation of 2-hydroxy-4-ethoxyacetophenone with 1A-butane diol in the presence of polyphosphoric acid as a catalyst at 145°C for 10 h. The synthesized resin was used to synthesize its polychelates with 4fblock
elements. The resin and its polychelates were characterized on the basis of elemental analyses, electronic spectra, magnetic susceptibilities, FTIR, NMR, and thermogravimetry analyses data. Morphological studies of the resin and its polychelates
were carried out by scanning electron microscope (SEM). Number average molecular weight (Mn) was measured by vapour pressure osmometry (VPO). Adsorption studies at different electrolyte concentrations, pH, and rates have been carried
out for 4f-block elements in the resin. It is observed that, the resin can be used as an efficient adsorption agent.
