Factorial design in the optimization of preconcentration procedure for lead determination by FAAS
(ELSEVIER SCIENCE BV, 2005)
The present paper proposes a preconcentration procedure for lead determination using flame atomic absorption spectrometry (FAAS). It is based on lead(11) ions extraction as brilliant cresyl blue (BCB) complex and its ...
Aluminium determination in environmental samples by graphite furnace atomic absorption spectrometry after solid phase extraction on Amberlite XAD-1180/pyrocatechol violet chelating resin
(ELSEVIER SCIENCE BV, 2004)
A chelating resin, pyrocatechol violet (PV) immobilised on an Amberlite XAD-1180 Support, was prepared and its use for the atomic absorption spectrometric determination of aluminium was investigated. The XAD-1180-PV resin ...
