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 ...
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 ...
Aluminium determination in environmental samples by graphite furnace atomic absorption spectrometry after solid phase extraction on Amberlite XAD-1180/pyrocatechol violet chelating resin
(ELSEVIER SCIENCE BV, 2004)
A chelating resin, pyrocatechol violet (PV) immobilised on an Amberlite XAD-1180 Support, was prepared and its use for the atomic absorption spectrometric determination of aluminium was investigated. The XAD-1180-PV resin ...
