A new ultrasound assisted extraction combined with dispersive liquid-liquid microextraction with solidification of floating organic drop (UAE-DLLME-SFO) method has been developed for the preconcentration of traces of triazine herbicides from fruit and vegetables. In UAE-DLLME-SFO, sonication for extraction of compounds from semisolid and solid matrices and a low-density and less-toxic solvent were used to overcome the disadvantages of conventional DLLME.
