De Gregori, Ida; Fuentes Pérez, Edwar; Olivares, Diego; Pinochet, Hugo (ROYAL SOC CHEMISTRY, 2004)Following our research on copper, arsenic and antimony in Chilean ecosystems, a study to understand the mobility and transport of these elements from soil to plants was carried out. So, the aim of this study, which follows ...

Fuentes Pérez, Edwar; Pinochet, Hugo; Potin-Gautier, Martine; De Gregori, Ida (AOAC INTERNATIONAL, 2004-01)This stability of Sb(Ill) and Sb(V) species was studied during,single extraction from soils by water. EDTA, diluted H2SO4 and H3PO4, and oxalic acid/oxalate solutions, with and without ascorbic acid, were used as stabilizing ...

Fuentes Pérez, Edwar; Pinochet, Hugo; De Gregori, Ida; Potin-Gautier, Martine (PERGAMON-ELSEVIER SCIENCE LTD, 2003-07-18)A sensitive atomic spectrometric method for the redox speciation analysis of antimony in soils is described. The method is based on the selective generation of stibine from Sb(III) in a continuous flow system using atomic ...
