Selective separation and preconcentration of copper in environmental samples onto Amberlite XAD-8 in a packed-bed column after complexation with a carbothioamide derivative
(Química Nova, 2013)
A new solid phase extraction (SPE) method has been developed for the selective separation and preconcentration of Cu (II) ions in food and water samples prior to its flame atomic absorption spectrometry determination. The ...
Tea-industry waste activated carbon, as a novel adsorbent, for separation, preconcentration and speciation of chromium
(Analytica Chimica Acta, 2011)
Activated carbon was produced from tea-industry wastes (TIWAC) and employed as a low cost and effective solid phase material for the separation, preconcentration and speciation of chromium species without using a complexing ...
Removal of phenol from aqueous solution by adsorption onto organomodified Tirebolu Bentonite: Equilibrium, kinetic and thermodynamic study
(Journal of Hazardous Materials, 2009)
A natural bentonite modified with a cationic surfactant, cetyl trimethylammonium bromide (CTAB), was used as an adsorbent for removal of phenol from aqueous solutions. The natural and modified bentonites (organobentonite) ...
Preconcentration, separation and spectrophotometric determination of aluminium(III) in water samples and dialysis concentrates at trace levels with 8-hydroxyquinoline–cobalt(II) coprecipitation system
(Journal of Hazardous Materials, 2010)
A separation-preconcentration procedure was developed for the determination of trace amounts of aluminium in water samples and dialysis concentrates by UV-vis Spectrophotometry after coprecipitation using 8-hydroxyquinoline ...
Biosorption of Rhodamine 6G from aqueous solutions onto almond shell (Prunus dulcis) as a low cost biosorbent
(Desalination, 2010)
This work presents an alternative methodology for removal of a dyestuff, Rhodamine 6G (R6G), from aqueous solutions by using a new biosorbent, almond shell (Prunus dulcis), in a batch biosorption technique. The characterization ...
Development a new solid phase extraction procedure for selective separation and enrichment of Au(III) in some environmental samples
(Journal of the Brazilian Chemical Society, 2013)
A highly sensitive, selective and low cost solid phase extraction (SPE) procedure was developed for separation and enrichment of Au(III) ions in environmental samples prior to its flame atomic absorption spectrometric ...
