in this study, we combined ionic liquid-based dispersive liquid liquid micro extraction (il-dllme) with faas for determining the palladium in different real samples at the trace level. 1-hexyl-3-methylimidazolium hexafluorophosphate [hmim][pf6] ionic liquid and 1-(2-pyridylazo) 2-naphthol (pan), were chosen as the extraction solvent and the chelating agent, respectively. the hydrophobic pd–pan ...

a facile and highly efficient method have been developed for the preconcentration of the mercury content in crude oil and gasoline samples after digestion with microwave-assisted digestion. octadecyl silica membrane disk has been modified by the recently synthesized triazene ligand, (e)-1-(2-ethoxyphenyl)-3-(4-nitrophenyl) triaz-1-ene (ent), then the modified membrane was used for the preconcen...

lithum can be de termined both by atomic absorption spectroscopy andflame emission spectroscopy. we have used the later method with a zeiss model pmqli spectro photometer fitt ed with ante-chamber atomizer and a potensiome rric line recorder. accurate ana lysis for the clement was acco mplished due to a sophisracared measuring instrument.
