Abstract: We report on the design of a UO22+-selective electrode based on the use of UO22+ imprinted polymer nanoparticles (IP-NPs), and its application for the differential pulse adsorptive cathodic stripping voltammetry determination of uranyl ions. A carbon paste electrode was modified with the IP-NPs, and differential pulse adsorptive cathodic stripping voltammetry was applied as the detection technique after open-circuit sorption of UO22+ ions. The modified electrode responses to UO22+ was linear in the 0.1 μg L-1 to 10 μg L-1 and in the 0.01 mg L-1 to 10 mg L-1. The method detection limit of the sensor was 0.03 μg L-1
