Abstract—This paper aims to optimize dispersive liquid-liquid Recently, a new liquid-liquid microextraction method microextraction based on the solidification of anic termed dispersive liquid-liquid microextraction (DLLME) was drop coupled with ultrasonic-assisted extraction (UAE-DLLME- developed by Rezaee et al. [8]. The DLLME method is a very SFO) of brominated diphenyl ether (BDE-209) in surficial simple and rapid method for extraction and preconcentration of sediment samples through ic algorithm pounds from water sample, and this method has (GANN) model and high-performance liquid chromatography been used to determine polycyclic aromatic hydrocarbons (HPLC). A GANN model was established based on the (PAHs) [8], pounds [9], triazine orthogonalized experiment of BDE-209. The average relative herbicides [10], chlorophenols [11], polychlorinated biphenyls deviation between the values predicted by GANN model and the (PCBs) [12]
