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 ...
Optimization of a new cloud point extraction procedure for the selective determination of trace amounts of total iron in some environmental samples
