Imprinting polymerization has been successfully utilized to make flocculants specific for heavy metal ions to improve heavy metal ion removal from wastewater. Different polymerization methods for hydrophilic and hydrophobic contaminants will be presented. Retention data for cadmium, mercury and cesium will be presented in the talk (only cadmium data will be shown in the preprint). The data demonstrate that imprinting improves heavy metal retention, but retention is highly dependent on surface area of the polymer. Porosity and swelling of these resins in water will also be discussed.
