Preliminary results of a quick, simple method of detecting antimony in water samples

Abstract

Abstract:Preliminary results of development of a direct and fast method of determination of antimony in samples of tap water using GFAAS are presented. The found levels of antimony were lower than permitted for human consumption. A mixture of Pd and Mg(NO 3 ) 2 (concentrations in the injected solution: 8.6 µg mL -1 and 5.8 µg mL -1 respectively) was used as the chemical modifier. The pyrolysis and atomization temperatures were 1000 and 1700ºC, respectively and the mean analytical recovery 98.2%. Warsaw and Springer-Verlag Berlin Heidelberg. © Versita

Selective separation and preconcentration of copper (II) in environmental samples by the solid phase extraction on multi-walled carbon nanotubes

“…Flame and/or graphite furnace atomic absorption spectrometry, inductively coupled plasma-optical emission spectrometry, inductively coupled plasma-mass spectrometry and electroanalytical techniques are the main instrumental techniques for the determination of traces heavy metal ions [17][18][19][20][21]. The presence of trace heavy metals lower than the detection limit limits of these instrumental techniques is one of the main problem [21][22][23][24].…”
