Abstract: In this research, a microextraction technique based on ionic liquids (ILs) termed in situ solvent formation microextraction (ISFME) was used for determination of nickel in solutions. 1‐(2‐pyridylazo)‐2‐naphtol (PAN) was chosen as a complexing agent. After preconcentration, the settled IL‐phase was dissolved in 50 μL of ethanol and aspirated into the flame atomic absorption spectrometer...
A simple in situ solvent formation microextraction methodology based on the application of ionic liquid (IL) as an extractant solvent and sodium hexafluorophosphate (NaPF 6 ) as an ion-pairing agent was proposed for the preconcentration of trace levels of cadmium. In this method cadmium was complexed with O,O-diethyldithiophosphate (DDTP) and extracted into an ionic liquid phase. After phase...
In this research, a novel microextraction technique based on ionic liquids (ILs) termed in situ solvent formation microextraction (ISFME) is developed. In this method, small amount of sodium hexafluorophosphate (NaPF 6 , as an ion-pairing agent) was added to the sample solution containing very small amount of 1-hexyl-3-methylimidazolium tetrafluoroborate ([Hmim][BF 4 ], as hydrophilic...
