“…Of these, metallic modifications remain crucial in the analysis of metal ions and have been well documented. Metal electrodes [40][41][42][43], metallic films [44][45][46][47] and metal nanoparticles [48][49][50] have been extensively studied to improve the detection efficiency of the AdSV technique. To date, all work dedicated to the electrochemical sensing of metals at paper-based sensing devices have been limited to ASV approaches.…”

The development of low-cost, disposable electrode materials has been at the forefront of sensor technology in recent decades. Paper, offers possibilities for multi-functional, disposable and economically friendly sensing capabilities and has proved to be a suitable reagent storage and substrate material in paper-based analytical devices (PADs). In this work, we report a simple inkjet printing procedure on photographic paper for the fabrication of single analyte electrochemical sensors. A three-electrode system, consisting of a 3 mm diameter working electrode (WE), a counter electrode (CE) and a reference electrode (RE) were prepared by inkjet printing of silver conductive inks for comparison to common commercial screen printed electrode (SPE) brands. In a second step, carbon coating and modification of the working electrode surface with an electrochemically reduced graphene oxide, gold nanoparticle (ERGO-AuNP) film, to improve electrode sensitivity and selectivity was employed. Improved electron-transfer kinetics, increased active surface area and enhanced catalytic properties were achieved due to the ERGO-AuNP layer inclusion. Electrical and topographical characterization of the printed layers was performed in the fabrication process. Printing of AgÀ NP ink showed good resistivity (1.8-6.3 Ω) on photographic paper. The prepared printed paper-based electrodes (PPE) offer a quantitative analysis of Ni(II), based on the accumulation of Ni(dmgH) 2 complexes at the modified electrode surface by squarewave adsorptive cathodic stripping voltammetry (SW-AdCSV). This study offers the first investigation on the feasibility of adsorptive electrochemical sensing methods at porous cellulose paper-based substrates. Instrumental parameters including deposition potential and deposition time were optimized for both electrochemical sensors. Improved sensitivities were achieved at the modified integrated electrodes over the unmodified derivate with a limit of detection (LOD) of 32.19 μg L À 1 achieved for the ERGO-AuNPÀ CCÀ AgÀ PPE. This is well below the EPA and WHO standards of 0.1 mg L À 1 or 0.1 ppm for Ni 2 + in drinking water.

The article reports on utilization of double deposition and stripping steps for increasing sensitivity of Cu(II) determination by anodic stripping voltammetry (ASV) at two lead film working electrodes. A significant preconcentration of copper was achieved thanks to utilization of a simple design of four electrodes system that gives possibility to perform one measurement cycle consisting of two deposition and two stripping steps. Due to the fact that deposition step is doubled, the concentration of Pb(II) needed to lead film electrodes formation was significantly reduced as compared to traditional procedures using three electrodes system. The analytical procedure of Cu(II) determination was optimized. The experimental factors: supporting electrolyte's pH and its concentration, lead ions concentration, potential and time of deposition at both working electrodes were studied. The Cu(II) peak current was linearly dependent on its concentration from 5×10−10 to 2×10−8 mol L−1 (deposition time of 270 and 160 s at the first and the second working electrode, respectively). The obtained detection limit for copper ions determination was 2.1×10−10 mol L−1. The described procedure was validated by analysis of two water certified reference materials. The described procedure was also utilized for real water sample analysis.
