Solvent-based de-emulsification dispersive liquid-liquid microextraction of palladium in environmental samples and determination by electrothermal atomic absorption spectrometry

► Separation of organic phase was achieved without using centrifugation. ► Applying low density 1-octanol as extraction solvents. ► Acetonitrile was introduced as a chemical demulsifier into the aqueous bulk. ► High extraction recovery and preconcentration are achieved in less than 2 min.
