Atomic absorption-spectrometric determination of copper, cadmium, lead and nickel in urine samples after enrichment and separation procedure on an activated carbon column
(DUSTRI-VERLAG DR KARL FEISTLE, 1999)
A sensitive and rapid chromatographic procedure which includes complexation of Cu, Ni, Cd and Pb with 1-(2-pyridylazo) 2-naphtol (PAN), adsorption of the metal-PAN complexes on the activated carbon column, and elution of ...
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 ...
