Functionalization of Synthetic Polymers by Supramolecular Compounds: Immobilization of Calix[n]arenes on Polyester

Schollmeyer, E.; Jansen, K.; Buschmann, H.-J.; Schmeide, K.

Calix[n]arenes are macrocyclic molecules synthesized by the base induced reaction of para-substituted phenols and formaldehyde. These ligands are known to form complexes with suitable guest substances. The selectivity of the calix[n]arenes is influenced by their size and functional groups. The present paper describes the preparation and application of calix[6]arene derivatives statistically functionalized with 1-alkyl groups at the upper rim. The separation of copper(II), nickel(II), cobalt(II) and uranium(VI) from aqueous solutions has been investigated by solvent extraction, as well as by using calix[6]arene-finished polyester felt. Uranium(VI) separation was studied as a function of pH value and uranium(VI) concentration. Furthermore, the recycling of calix[6]arene finished polyester felts loaded with uranium(VI) ions by elution with different solvents was examined. The suitability for the remediation of uranium contaminated water especially at low concentration levels was shown.
