Abstract

This article examines a simple and efficient method for extraction and preconcentration at the same time very low values of ORGANOCHLORINE (OCPS) in the river water samples, based on the specific situation of DISPERSIVE LIQUID-liquid microextraction in a long thin tube. The effect of influencing factors in microextraction such as the type and volume of solvents dispersive and extracted and volume of sample aqueous solution was studied and optimized. In the optimized qualification, mixture of 2.5 ml acetone and 0.5 ml n-hexane and toluene (1:1) for 30 seconds to 19 ml water solution is injected into the pipe and formed cloudy solution and toxins transferred to the organic phase and reached the top of the column. Finally, after extraction and cleanup 1 ul of samples injected into GAS CHROMATOGRAPHY FLAME IONIZATION and compared to standard solutions curve, were determined. Under optimal conditions, the linear range of calibration curves in the range of 0.6 to 1.4 ug/ml and relative recovery of 93.1 to 98.6, relative standard deviation much lower than 5.9% and correlation coefficient of 0.95 was calculated. The limit of detection and quantification limits, respectively, in the range of 0.8 to 1.3 and 3.1 to 3.7 ug/l respectively. The advantage of this method is the simplicity, speed, low cost and high recovery percentage.
