Application of factorial design in optimization of nickel preconcentration by solid phase extraction and its determination in water and food samples by flame atomic absorption spectrometry
(CANADIAN SOC ANALYTICAL SCIENCES & SPECTROSCOPY, 2007)
A procedure for the preconcentration and determination of trace nickel in water and food samples using flame atomic absorption spectrometry (FAAS) is presented. It is based on column solid-phase extraction of nickel(II) ...
Separation/preconcentration of Zn(II), Cu(II), and Cd(II) by Saccharomyces carlsbergensis immobilized on silica gel 60 in various samples
(TAYLOR & FRANCIS INC, 2006)
This study presents a solid phase extraction procedure based on column biosorption of Zn(II), Cu(II), and Cd(II) ions on Saccharomyces carlsbergensis immobilized on silica gel 60. The analytes were determined by flame ...
Penicillium digitatum immobilized on pumice stone as a new solid phase extractor for preconcentration and/or separation of trace metals in environmental samples
(ELSEVIER SCIENCE BV, 2008)
This study presents a column solid phase extraction procedure based on column biosorption of Cu(II), Zn(II) and Pb(H) ions on Penicillium digitatum immobilized on pumice stone. The analytes were determined by flame atomic ...
Application of full factorial design for the preconcentration of chromium by solid phase extraction with Amberlyst 36 resin
(SPRINGER WIEN, 2008)
The preconcentration of chromium(III) by solid phase extraction and its determination from aqueous solutions by flame atomic absorption spectrometry (FAAS) is investigated by applying an experimental design. The optimization ...
