Abstract: In the present study, an alternative platform for trace copper ions (Cu(II)) determination using a diamond electrode in combination with a disposable paper-based analytical device (d-PAD) has been proposed. First, the complexation between Cu(II) and 1,10-phenanthroline ligand was adsorptively accumulated onto a paper that is directly in contact with the diamond electrode and measured via square wave anodic stripping voltammetry. Under the optimal experimental conditions, the peak current was proportional to the concentration of Cu(II) in the range of 0.4–70 ng mL−1, and the detection limit was found to be 0.1 ng mL−1. Most importantly, this platform can be successfully applied to detect trace Cu(II) in different water samples (drinking water, tap water, groundwater and river water) with satisfactory results. Thus, the proposed d-PAD could be a highly efficient platform for trace Cu(II) determination in environmental samples. © 2020 Wiley-VCH GmbH
