Abstract: A dysprosium(III)-imprinted polymer was prepared by an imprinting method using dysprosium(III) as the guest and styrene and methacrylate as the host, via a seed emulsion technique. The dysprosium(III)-imprinted polymer adsorbed dysprosium(III) ions more effectively than a non-imprinted polymer. The dysprosium(III) ion-selective liquid membrane electrode, comprising the dysprosium(III)-imprinted polymer (20 mg), polyvinyl chloride (75 mg), and plasticizer nitrophenyl octyl ether (80 mg), showed a Nernstian response of 19.3 mV dec-1 in the range of 10-7 - 10-2 M. The selectivity coefficients of this electrode (log kpot) for potassium(I), copper(II), and samarium(III) ions were -3.71, -5.29, and -3.85, respectively. The electrode was also used for the determination of dysprosium(III) in river water
