    • Determination of free metal ion concentrations using screen-printed electrodes and AGNES with the charge as response function 

      Parat, C.; Aguilar Camaño, David; Authier, L.; Potin-Gautier, M.; Companys Ferran, Encarnació; Puy Llorens, Jaume; Galceran i Nogués, Josep (Wiley, 2011)
      AGNES (Absence of Gradients and Nernstian Equilibrium Stripping) has been implemented with screen-printed electrodes (SPE) for the determination of the free concentration of Zn2+, Cd2+ and Pb2+. For SPE, the stripped charge ...

    • Determination of free metal ion concentrations with AGNES in low ionic strength media 

      Aguilar Camaño, David; Parat, C.; Galceran i Nogués, Josep; Companys Ferran, Encarnació; Puy Llorens, Jaume; Authier, L.; Potin-Gautier, M. (Elsevier, 2013-01-15)
      The determination of free metal ion concentrations of heavy metals, like Zn2+ or Cd2+, with AGNES (Absence of Gradients and Nernstian Equilibrium Stripping) requires an adequate selection of parameters such as deposition ...

    • Free Zn2+ determination in natural freshwater of the Pyrenees: towards on-site measurements with AGNES 

      Parat, C.; Authier, L.; Castetbon,A.; Aguilar Camaño, David; Companys Ferran, Encarnació; Puy Llorens, Jaume; Galceran i Nogués, Josep; Potin-Gautier, M. (CSIRO Publishing, 2015)
      An on-site methodology has been developed for the direct determination of free Zn2+ with AGNES (Absence of Gradients and Nernstian Equilibrium Stripping) in freshwaters. This implementation includes: i) the use of screen ...

    • Non-purged voltammetry explored with AGNES 

      Aguilar Camaño, David; Galceran i Nogués, Josep; Companys Ferran, Encarnació; Puy Llorens, Jaume; Parat, C.; Authier, L.; Potin-Gautier, M. (Royal Society of Chemistry, 2013)
      The reduction of oxygen increases pH in the surroundings of an electrode. A theoretical model estimates the steady-state pH profile from the surface of the electrode up to the bulk solution. A very simple formula predicts ...
