Journal ArticleDOI
Cork biomass as biosorbent for Cu(II), Zn(II) and Ni(II)
TL;DR: In this article, the removal of heavy metal from solutions using biosorption in cork powder is described, along with the effect of different variables, such as the solid-liquid ratio, temperature and pH on the removal efficiency of the metals.
Journal ArticleDOI
Iron recovery from sulphate leach liquors in zinc hydrometallurgy
TL;DR: In this article, solvent extraction is investigated as a promising alternative for the recovery of iron from leach solutions, which is usually carried out by precipitation as jarosite, goethite or hematite.
Journal ArticleDOI
Heavy metals biosorption on cork biomass: effect of the pre-treatment
TL;DR: The effect of pre-treatment of cork biomass on the biosorption of heavy metals (Cu, Zn and Ni) was studied in this article, where the Fisher reaction confirmed the important role of carboxylic groups in the binding of the heavy metals.
Journal ArticleDOI
Recovery of phenol from aqueous solutions using liquid membranes with Cyanex 923
TL;DR: In this article, the effect of the aqueous and organic flow rates on the overall mass transfer coefficient for extraction was determined and the experimental values of the overall Mass Transfer Coefficient (MTC) for extraction were found in agreement with the ones predicted from the conventional resistance in series model.

TL;DR: In this paper, the effect of pre-treatment of cork biomass with a hydrochloric acid solution on its sorption affinity towards uranium was investigated and the results showed that the conversion of cORK biomass into the H-form by the acid wash allowed to increase the sorption capacity towards uranium more than twice, due to the increase of the concentration of strong acidic and weak acidic groups on its surface.
