The determination is based on the continuous liquid-liquid extraction of the copper(I)/ 6-methylpicolinealdehyde azine/perchlorate ion-pair into 4-methyl-2-pentanone in a flowinjection manifold. The organic extract fills a loop of an injector situated in an integrated feed system of an atomic absorp

The flow manifold described allows automatic extraction of metal ions in aqueous samples into 4-methyl-2-pentanone with ammonium pyrrolidinedithiocarbamate as an extracting agent. The organic extract is led into the loop of an injector situated in an integrated feed system of an atomic absorption sp
A method for determining traces of bismuth(II1) in environmental samples by graphite furnace atomic absorption spectrometry (GFAAS) after extractive separation with trioctylmethylammonium nitrate (TOMA \* NO,) is described. Bismuth(II1) was quantitatively extracted and concentrated with 6% (w/v) TOM
## How-injection atomic spectrometry with sorbent extraction preconcentration is applied to the simultaneous determination of iron and i&III). Upon injection of a sample containing iron in both oxidation states, iron(III) is directly carried to the flame atomic absorption spectmmeter whereas the i
