On-line preconcentration and determination of chromium in parenteral solutions by flow injection - Flame atomic absorption spectrometry
(Elsevier Science, 2003-02)
An on-line chromium preconcentration and determination system implemented with flame atomic absorption spectrometry (FAAS) associated to flow injection (FI) was studied. For the retention of chromium, 4-(2-Thiazolylazo)-resorcinol ...
Determination of Cr(VI) and Cr(III) species in parenteral solutions using a nanostructured material packed-microcolumn and electrothermal atomic absorption spectrometry
(Elsevier Gmbh, 2009-07)
A sequential on-line preconcentration and separation system for Cr(VI) and Cr(III) species determination was developed in this work. For this purpose, a microcolumn filled with nanostructured α-alumina was used for on-line ...
