Synthesis and characterization of a molecularly imprinted polymer for Pb2+ uptake using 2-vinylpyridine as the complexing monomer

Molecularly imprinted polymer (MIP) particles for selective extraction of Pb2+ ion from aqueous media were prepared using non-covalent molecular imprinting methods. 2-vinylpyridine was chosen as the complexing monomer. The imprinted polymer was synthesised by radical polymerisation. The template (Pb...
