Full TextAbstract
Directly suspended droplet microextraction technique (DSDME) coupled with GC–FID was used to determine BTEX compounds in aqueous samples. The effective parameters were optimized. The performance of the proposed technique was evaluated for the determination of BTEX compounds in natural water samples. Under the optimal conditions the enrichment factors ranged from 142.68 to 312.13, linear range; 0.01–20 µg L-1, limits of detection; 0.0008–0.010 µg L-1 for most of analytes. Relative standard deviations for 2 µg L-1 of BTEX in water were in the range 1.81–2.47% (n = 5). The recoveries of BTEX from surface water at spiking level of 5.0 µg L-1 were 89.87– 98.62%.
