In this article, a new method using homogeneous liquid-liquid microextraction via flotation assistance (HLLME-FA) combined with gas chromatography-flame ionization detection (GC-FID) for the determination of butachlor in water samples was developed. In this research, a special extraction cell was designed to facilitate collection of the low-density solvent extraction. No centrifugation was required in this procedure. The water sample solution was added into the extraction cell which contained an appropriate mixture of extraction and homogeneous solvents. By using air flotation, the organic solvent was collected at the conical part of the designed cell. The effect of different parameters on the efficiency of the extraction such as kind and the volume of extraction and homogeneous solvents, ionic strength, and extraction time were studied and optimized. Under the optimum conditions, the calibration graph was linear in the range of 1.0-200 mu g L-1 with the detection limit of 0.2 mu g L-1. The results show that HLLME-FA is a simple, rapid, sensitive, and efficient analytical method for the determination of butachlor in water samples, and satisfactory results were obtained.
