Description 30-37
A new chelating polymer functionalized with 2-methoxy-1-imidazolylzobenzene has been synthesized and characterized by elemental analysis, infrared spectra, thermogravimetric analysis, hydrogen ion capacity and sorption capacity for different metal ions. The sorption capacity of the resin towards Fe(III), Cu(II), Zn(II), Cd(II) and Pb(II) as a function of pH has been studied. The resin exhibits no affinity for alkali or alkaline earth metal ions. Separation and estimation of lead in trace quantities in road dust and different biological samples at pH 3.0 by AAS has been carried out. Determination of iron in river water at pH 5.0 and removal of Fe(III) from well-water spiked with ⁵⁹Fe as tracer have
been successfully performed using this resin. LOD (corresponding to 3σ) for Fe(III) is 0.05 mg L⁻¹ and that
for Pb(II) is 0.08 mg L⁻¹.
