    • Oligo and polyuronic acids interactions with hypervalent chromium 
      González, J. C.; García, S. I.; Bellú, Sebastián; Atria Salas, Ana María; Salas Pelegrin, Juan Manuel; Rockenbauer, A.; Korecz, L.; Signorella, Sandra; Sala, Luis F. (PERGAMON-ELSEVIER SCIENCE LTD, 2009-09-02)
      Selective oxidation of galacturonic residues of oligo and polyuronic acids by Cr-VI affords CO2/HCO2H, oxidized uronic acid, and Cr-III as final redox products. Kinetic studies show that the redox reaction proceeds through ...
    • Removal of chromium(VI) and chromium(III) from aqueous solution by grainless stalk of corn 
      Bellú, Sebastián; García, Silvia; González, Juan C.; Atria Salas, Ana María; Sala, Luis F.; Signorella, Sandra (TAYLOR & FRANCIS INC, 2008)
      Grainless stalk of corn (GLSC) was tested for removal of Cr(VI) and Cr(III) from aqueous solution at different pH, contact time, temperature, and chromium/adsorbent ratio. The results show that the optimum pH for removal ...
    • Synthesis, structure and antifungal properties of Co(II)-sulfathiazolate complexes 
      Bellú, Sebastián; Hure, Estela; Trapé, Marcela; Trossero, Claudia; Molina, Gabriel; Drogo, Claudia; Williams, Patricia; Atria Salas, Ana María; Muñoz, Juan Carlos; Zacchino, Susana; Sortino, Maximiliano; Campagnoli, Darío; Rizzotto, Marcela (PERGAMON-ELSEVIER SCIENCE LTD, 2005-03-10)
      he reaction between sulfathiazole and cobalt(II) leads to a pink solid, [Co-II(ST)(2)(H2O)(4)] (1), which, after 7-10 days in the mother solution, transforms into red crystals of [Co-II(ST)(2)(H2O)(3)](n) (2) (ST = ...
