(a) Repeatability test: multiple SW-ASV voltammograms registrations obtained with the same presorbed Zn(II) PAA-g-PVDF nanoporous membrane-electrode; (b) reproducibility test: triplicate experiments utilizing three different batches of PAA-g-PVDF nanoporous membrane-electrodes—for (a) and (b) tests, presorptions were performed in 200 ppb Zn(II) spiked synthetic water solutions; (c) multiple-ion detection: registered SW-ASV voltammogram of a presorbed PAA-g-PVDF nanoporous membrane-electrode in an aqueous solution composed of 50 g L\(^{-1}\) NaCl, 200 ppb Zn(II), 200 ppb Pb(II) and 200 ppb Cu(II)—Electrolyte: 0.1 M buffered acetate, pH 5.5.
