Assessment of labilities of metal complexes with the dynamic ion exchange technique
Quattrini, Federico; Galceran i Nogués, Josep; Rey Castro, Carlos; Puy Llorens, Jaume; Fortin, Claude (CSIRO Publishing, 2019)The dynamic ion exchange technique (DIET) is proposed to provide speciation information, which can be used to establish links with metal bioavailability in natural waters. The experimental setup consists of a few milligrams ... -
Dissolution and phosphate-induced transformation of ZnO nanoparticles in synthetic saliva probed by AGNES without previous solid-liquid separation. Comparison with UF-ICP-MS
David, Calin; Galceran i Nogués, Josep; Quattrini, Federico; Puy Llorens, Jaume; Rey Castro, Carlos (American Chemical Society, 2019-02-26)The variation over time of free Zn2+ ion concentration in stirred dispersions of ZnO nanoparticles (ZnO NPs) prepared in synthetic saliva at pH 6.80 and 37 degrees C was followed in situ (without solid liquid separation ... -
Dynamics of trace metal sorption by an ion-exchange chelating resin described by a mixed intraparticle/film diffusion transport model. The Cd/Chelex case
Quattrini, Federico; Galceran i Nogués, Josep; David, Calin; Puy Llorens, Jaume; Alberti, Giancarla; Rey Castro, Carlos (Elsevier, 2017-06-01)The time-evolution of Cd2+ ion sorption by Chelex 100 resin was studied in batch experiments as a function of time, pH, ionic strength, stirring rate, mass of resin and initial metal ion concentration. In the experimental ... -
