Evaluation of hyper-cross-linked polymeric sorbents (Macronet MN200 and MN300) on dye (Acid red 14) removal process
(2008-03)
Article
Restricted access - publisher's policyPolymeric supports are presented as an alternative to granular activated carbon (GAC) for organic contaminants removal from waste waters from industrial processes. The present work describes the sorption of an azo dye (Acid ... -
Exploration of geochemical data with compositional canonical biplots
(2018-07-25)
Article
Restricted access - publisher's policyThe study of the relationships between two compositions is of paramount importance in geochemical data analysis. This paper develops a compositional version of canonical correlation analysis, called CoDA-CCO, for this ... -

Open AccessEl Batolito hercinico de Ricobayo, al que se encuentran asociadas genéticamente mineralizaciones de estaño, ha sido objeto de un estudio litogeoquimico con el fin de comprobar la efectividad de tales metodos en la ... -
Sorption of antimony (V) onto synthetic goethite in carbonate medium
(2008-06)
Article
Restricted access - publisher's policyThe sorption kinetics of antimony(V) on synthetic goethite is very fast compared to the sorption of other metals on goethite (e.g. arsenic and selenium) and depends on temperature, with an activation energy of 49+9 kJ . ... -
Sorption of selenium(IV) and selenium(VI) onto natural iron oxides: Goethite and hematite
(Elsevier, 2008-01)
Article
Restricted access - publisher's policySelenium is a toxic element with a relatively high mobility in the natural waters. Iron oxy-hydroxides might play an important role in the migration of this element as well as on its removal from contaminated water. In ... -
