Determination of lead and cadmium using an ionic liquid and dispersive liquid-liquid microextraction followed by electrothermal atomic absorption spectrometry

► DLLME can be carried out without the need of organic volatile solvents. ► An ionic liquid obtained in situ by mixing two precursors can be used for extraction. ► The conjunction of IL-DLLME and ETAAS results in a sensitive procedure for Pb and Cd.
