ABSTRACT
ve To increase the analytical efficacy and the sensitivity of determination of trace chloroform and tetrachloro-methane in water. Methods Headspace solid phase microextraction (HSSPME) analysis was applied to replace the traditional headspace method in determination of trace chloroform and tetrachloro-methane in water. Results The lowest detection limits were 0.05?g/L for chloroform and 0.005?g/L for tetrachloro-methane respec-tively. The precisions and accuracies all accorded with the requirements of determination. Conclusion The method of HSSPME was easy and rapid to operate, revealed reliable and accurate results and good practicability. It also showed higher sensitivity without any organic solvent, compared with that of traditional headspace method.
