Enrichment and determinations of nickel(II), cadmium(II), copper(II), cobalt(II) and lead(II) ions in natural waters, table salts, tea and urine samples as pyrrolydine dithiocarbamate chelates by membrane filtration-flame atomic absorption spectrometry combination
(ELSEVIER SCIENCE BV, 2003)
A membrane filtration procedure for the preconcentration of nickel(II), cadmium(II), copper(H), cobalt(II) and lead(II) ions has been established. The analytes were adsorbed on cellulose nitrate membrane filter as their ...
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 ...
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), ...
