    • Free indium concentration determined with AGNES 

      Tehrani, Marjan H.; Companys Ferran, Encarnació; Dago Busquets, Àngela; Puy Llorens, Jaume; Galceran i Nogués, Josep (Elsevier, 2018)
      Indium is increasingly used in electronic devices, from which it can be mobilized towards environmental compartments. Speciation of In in waters is important for its direct ecotoxicological effects, as well as for the fate ...
    • Free Zn2+ determination in systems with Zn-Glutathione 

      Lao, Mireia; Dago Busquets, Àngela; Serrano, N.; Companys Ferran, Encarnació; Puy Llorens, Jaume; Galceran i Nogués, Josep (Elsevier, 2015-11-01)
      Zn-Glutathione speciation was studied applying the electrochemical technique AGNES (Absence of Gradients and Nernstian Equilibrium Stripping) to determine the free zinc concentration. In titrations varying either pH, total ...
    • New methodology to measure low free indium (III) concentrations based on the determination of the lability degree of indium complexes. Assessment of In(OH)3 solubility product 

      Tehrani, Marjan H.; Companys Ferran, Encarnació; Dago Busquets, Àngela; Puy Llorens, Jaume; Galceran i Nogués, Josep (Elsevier B.V., 2019)
      The vast industrial and consumer application of indium (solar cells, displays, etc.) risks its eventual leakage to the environment. Given the relevant role of speciation on the ecotoxicological effects of a certain total ...
