New polymeric membrane (PME) and coated graphite (CGE) copper(II)-selective electrodes based on 1-hydroxy-2-(prop-2′-enyl)-4-(prop-2′-enyloxy)-9,10-anthraquinone were prepared. The electrodes reveal linear emf-pCu²⁺ responses over wide concentration ranges (1.0 × 10^-5 - 1.0 × 10^-1 M with a slope of 27.3 mV decade^-1 for PME and 8.0 × 10^-8 - 5.0 × 10^-2 M with a slope of 29.1 mV decade^-1 for CGE) and very low limits of detection (8.0 × 10^-6 M for PME and 5.0 × 10^-8 M for CGE). The potentiometric response is independent of the pH of the test solution in the pH range 3.0 - 6.0. The proposed electrodes possess very good selectivities over a wide variety of other cations, including alkali, alkaline earth, transition and heavy metal ions, the selectivity coefficients for the CGE being much improved over those for the PME. The electrodes were used as indicator electrodes in the potentiometric titration of Cu²⁺ and in the recovery of copper ions from wastewater.
