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 ...
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 ...
Traffic pollution in Nigde-Turkiye: Investigation of trace element contents of soil samples
(INST LEBENSMITTELTECHNOLOGIE ANALYTISCHE CHEMIE, 1997)
A study was performed to determine the levels of heavy metals pollution originated from the traffic of Nigde-Turkiye. Trace element contens of the soil samples collected from the five stations of Nigde City were determined ...
Rubidium and strontium levels of natural water samples from the Middle Anatolia Region of Turkey
(ACADEMIC PUBLICATION COUNCIL, 1998)
Rubidium and strontium contents of water samples collected from the Central Region of Anatolia have been determined by flame atomic emission spectrometry (FAES). The results found by FAES were compared with the results ...
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 ...
Trace enrichment and atomic absorption spectrometric determination of lead, copper, cadmium and nickel in drinking water samples by use of an activated carbon column
(MARCEL DEKKER INC, 1997)
A simple method for atomic absorption spectrometric determination of lead copper, cadmium and nickel in drinking water samples after preconcentration by sorbing 1-(2-pyridylazo) 2-naphthol (PAN) complex of these metals on ...
Heavy metals in black tea samples produced in Turkey
(SPRINGER-VERLAG, 2004)

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 ...
