Exploiting the use of 3,4-HPO ligands as nontoxic reagents for the determination of iron in natural waters with a sequential injection approach.
TL;DR: The advantage of using minimal consumption values associated with sequential injection, together with the lack of toxicity of 3,4-HPO ligands, enabled to present a greener chemistry approach for iron determination in environmental samples within the range 0.10-2.00 mg Fe/L with a LOD of 7 μg/L.
Journal ArticleDOI
Sorption behavior of uranium from Sulfate media using purolite A400 as a strong base anion Exchange resin
TL;DR: In this article, the sorption characteristics of uranium on a strongly basic anion exchanger, Purolite A400, were investigated, before and after sorption of uranium, and the characteristics of the anion were compared.
Journal ArticleDOI
Modeling biosorption of Cr(VI) onto Ulva compressa L. from aqueous solutions.
TL;DR: The thermodynamic parameters indicated an endothermic heat and a spontaneity of the Cr(VI) biosorption onto ECL and the pseudo-second order model describes suitably the experimental data.
Journal ArticleDOI
A kinetic study on solvent extraction of samarium from nitrate solution with D2EHPA and Cyanex 301 by the single drop technique
TL;DR: In this article, the reactive extraction of Sm(III) from aqueous nitrate solution with D2EHPA and Cyanex 301 in kerosene was investigated by single drop column method.
