XAD-4/PAN solid phase extraction system for atomic absorption spectrometric determinations of some trace metals in environmental samples
(TAYLOR & FRANCIS INC, 2004)
A simple, fast, and sensitive column solid phase extraction study has been proposed for flame atomic absorption spectrometric determination of lead, cadmium, chromium, nickel, copper, and manganese ions on XAD-4 as ...
Determination of trace metal ions by AAS in natural water samples after preconcentration of pyrocatechol violet complexes on an activated carbon column
(ELSEVIER SCIENCE BV, 2000)
A simple preconcentration method is described for the determination of Cu, Mn, Co, Cd, Pb, Ni and Cr in water samples by flame AAS. Trace metal ions in water were sorbed as pyrocatechol violet complexes on activated carbon ...
Preconcentration-separation of heavy metal ions in environmental samples by membrane filtration-atomic absorption spectrometry combination
(MARCEL DEKKER INC, 2004)
The preconcentration performance characteristics of cellulose nitrate membrane filter were investigated for the atomic absorption spectrometric determinations of traces metal ions in the environmental samples. The method ...

The uses of 1-(2-pyridylazo) 2-naphtol (PAN) impregnated Ambersorb 563 resin on the solid-phase extraction of traces heavy metal ions and their determinations by atomic absorption spectrometry
(ELSEVIER SCIENCE BV, 2003)
1-(2-pyridylazo) 2-naphtol (PAN) impregnated Ambersorb 563 resin was used as solid phase extractor of copper, nickel, cadmium, lead, chromium and cobalt ions in aqueous solutions prior to their atomic absorption spectrometric ...
Speciation of Cr(III) and Cr(VI) in tannery wastewater and sediment samples on Ambersorb 563 resin
(MARCEL DEKKER INC, 2002)
A simple method has been established for speciation of chromium(III) and chromium(VI) in natural water samples. The method is based on the solid phase extraction of the Cr(VI)-APDC chelate on the Ambersorb 563 carbonaceous ...
Preparation of a chelating resin by immobilizing 1-(2-pyridylazo) 2-naphtol on amberlite XAD-16 and its application ' of solid phase extraction of Ni(II), Cd(II), Co(II), Cu(II), Pb(II), and Cr(III) in natural water samples
(MARCEL DEKKER INC, 2003)
A polystyrene divinylbenzene resin (Amberlite XAD-16) functionalized by 1-(2-pyridylazo) 2-naphtol has been synthesized and its sorption properties have been investigated for preconcentration of Ni(II), Cd(II), Co(II), ...
Separation and enrichment of chromium, copper, nickel and lead in surface seawater samples on a column filled with amberlite XAD-2000
(MARCEL DEKKER INC, 2001)
A separation/enrichment procedure has been established for atomic absorption spectrometric determination of some trace metal ions by using a column filled Amberlite XAD-2000 resin. It is based on the sorption of metal ions ...
Comparison of sample preparation procedures for the determination of trace heavy metals in house dust, tobacco and tea samples by atomic absorption spectrometry
(WILEY-V C H VERLAG GMBH, 2004)
The effect of wet ashing, dry ashing and microwave procedure for the determination of trace metal levels was investigated in house dust, tobacco and tea samples by atomic absorption spectrometry. The study of sample ...
