Abstract:
Cross-linked terpolymers made up of phenol, diaminoalkane and formaldehyde monomeric units. The cross-linked terpolymers are synthesized via a Mannich mechanism in n-heptane, characterized with multiple spectroscopic techniques, scanning electron microscopy and powder X-ray diffraction, and are also investigated for their Pb 2+  adsorption capacity and thermodynamic properties. A method of removing Pb 2+  ions from an aqueous solution or a wastewater sample with these cross-linked terpolymers is also described.

Claim (Index 8):
A method of removing Pb 2+  ions from an aqueous solution, comprising:\n contacting, at a pH of 4-6, the aqueous solution with an adsorbent \n in the form of a powder or pellets, \n wherein the adsorbent comprises a cross-linked terpolymer comprising polycondensed units of phenol, a diaminoalkane and formaldehyde; \n wherein the diaminoalkane has a formula according to Formula 1: \n with m, representing the number of carbon atoms in an alkyl chain, is 4, 6, or 8; and wherein each terminal amino group of the diaminoalkane unit bridges the aryl group of the phenol unit through a nitrogen-carbon-aryl linkage.
