The functional resins with amino ligands were synthesized by the modification of vinylbenzyl chloride- divinylbenzene copolymers gels (VBC/DVB) with the aliphatic and aromatic amines. Two methods of modification were employed, the first one was traditional heating of the polymer with either neat amine or amine solution in an appropriate solvent, the second method was heating of reaction mixture in a microwave reactor. These polymeric materials were characterized using nitrogen and chlorine elemental analysis. The polymeric resins were used for the removal of gold from ammonium buffer that contains 100 g/L NHrH20 and 50.0 g/L (NIL^SO.!. All resins were highly selective for the gold(I) from ammonia solution and they did not sorb ammine complexes of copper(II).
