Application of solid-phase extraction for the preconcentration and separation of trace amounts of cobalt from urine
(DUSTRI-VERLAG DR KARL FEISTLE, 2001)
A solid-phase extraction method using 4-(2-thiazolylazo) resorcinol (TAR) as chelating agent on Amberlite XAD-16 column has been used for separation/preconcentration of trace amounts of cobalt prior to its determination ...
Atomic absorption spectrometric determination of copper, cobalt, cadmium, lead, nickel and chromium in table salt samples after preconcentration on activated carbon
(ACADEMIC PUBLICATION COUNCIL, 2001)
Copper, cobalt, cadmium, lead, nickel, and chromium contents of table salt samples were determined by atomic absorption spectrometry after preconcentration/separation on an activated carbon column as pyrocatechol violet ...
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 ...
