Abstract
New 1,3-alternate calix[4]arenecrown-6 and calix[4]arenecrown-5, which are selective for caesium and potassium ions respectively, have been synthesized and linked covalently to silica gel via hydrosilanization and successfully employed for the chromatographic separation of Cs+ and K+ from alkali metal ions.Keywords
