A method of creating a cationic molecularly imprinted polymer bead that can bind inorganic target compounds is disclosed and described. The cationic molecularly imprinted polymer bead can be formed by complexing a target compound with a cationic ligand, polymerizing the cationic ligands to form the bead, and then extracting the target compound from the bead. The cationic ligand complex can have an octanol water partition coefficient of about 1 to about 10. The cationic molecularly imprinted polymer bead can have a porous structure containing a plurality of complexing cavities for selectively bind specific target compounds for removal from potable water, mine effluent, industrial effluent, or other fluids.
