    • Effects of a mixture of ligands on metal accumulation in diffusive gradients in thin films (DGT) 

      Altier Infantes, Alexandra; Jiménez-Piedrahita, Martín; Uribe Kaffure, Ramiro; Rey Castro, Carlos; Cecilia Averós, Joan; Galceran i Nogués, Josep; Puy Llorens, Jaume (CSIRO Publishing, 2018)
      Natural waters contain mixtures of ligands, which collectively affect the availability of trace metals. The individual contribution of each complex to the overall metal flux received by a sensor can be described in terms ...
    • Limits of the Linear Accumulation Regime of DGT Sensors 

      Mongin, Sandrine; Uribe Kaffure, Ramiro; Rey Castro, Carlos; Cecilia Averós, Joan; Galceran i Nogués, Josep; Puy Llorens, Jaume (American Chemical Society, 2013)
      A key question for the practical application of DGT (Diffusive Gradients in Thin films) as dynamic sensors in the environmental monitoring of trace metals is the influence of pH and dissolved ligands over the linear ...
    • Numerical Simulation of Non-Linear Models of Reaction—Diffusion for a DGT Sensor 

      Cecilia Averós, Joan; Puy Llorens, Jaume; Uribe Kaffure, Ramiro (MDPI, 2020-04-20)
      In this work, we present a novel strategy for the numerical solution of a coupled system of partial differential equations that describe reaction–diffusion processes of a mixture of metals and ligands that can be absorbed ...
