Resistant ionic liquid-based dispersive liquid–liquid microextraction (IL-based DLLME) method is described for sensitive determination of trace amounts of rhodamine B in aqueous samples containing very high salt concentrations by fiber optic-linear array detection spectrophotometry (FO-LADS). The method is based on the DLLME of rhodamine B from aqueous solution using ionic liquid. The robustness of...
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...
