Journal ArticleDOI
Arsenic sorption onto natural hematite, magnetite, and goethite.
TL;DR: The main trend observed in the variation of the arsenic sorbed with pH is the decrease of the sorption on the three sorbents at alkaline pH values, which agrees with results found in the literature.
Journal ArticleDOI
Sorption of Pb(II), Ni(II), Cu(II) and Cd(II) from aqueous solution by olive stone waste
Núria Fiol,Isabel Villaescusa,María del Rosario Martínez Martínez,Nuria Miralles,Jordi Poch,Joan Serarols +5 more
TL;DR: In this paper, the effect of contact time, solution pH, ionic medium and initial metal concentration were studied in batch experiments at room temperature, and the results showed that olive stone waste, which has a very low economical value, may be used for the treatment of wastewaters contaminated with heavy metals.
Journal ArticleDOI
Removal of copper and nickel ions from aqueous solutions by grape stalks wastes
Isabel Villaescusa,Núria Fiol,María del Rosario Martínez Martínez,Nuria Miralles,Jordi Poch,Joan Serarols +5 more
TL;DR: Sorption of copper and nickel on grape stalks released an equivalent amount of alkaline and alkaline earth metals (K+, Mg2+, Ca2+) and protons, indicating that ionic exchange is predominantly responsible for metal ion uptake.
Journal ArticleDOI
Removal of lead(II) and cadmium(II) from aqueous solutions using grape stalk waste.
María del Rosario Martínez Martínez,Nuria Miralles,Soraya Hidalgo,Núria Fiol,Isabel Villaescusa,Jordi Poch +5 more
TL;DR: From the results obtained it seems that other mechanisms, such as surface complexation and electrostatic interactions, must be involved in the metal sorption in addition to ion exchange.
Journal ArticleDOI
Sorption of selenium(IV) and selenium(VI) onto natural iron oxides: goethite and hematite.
Miquel Rovira,Javier Giménez,María del Rosario Martínez Martínez,Xavier Martínez-Lladó,Joan de Pablo,V. Martí,Lara Duro +6 more
TL;DR: This work study the interaction of Se(IV), and Se(VI) with natural iron oxides hematite and goethite through two series of batch experiments at room temperature using a triple layer surface complexation model and using the FITEQL program.
