Abstract: |
A new method for determination of o-dichlorobenzene in the soil samples has been developed using the ionic liquid 1–butyl-3–methyl-imidazole hexafluorophosphate for the headspace single-drop liquid-phase micro extraction with gas chromatography analysis. Experimental parameters affecting the performance of extraction are studied including media types inspected the solution, pH, extraction time, temperature and salt effect. The results show that extraction time and temperature are the main influencing factors. Under the optimum extraction conditions, limit of detection is 0.028 μg g-1, and the measured value of o-dichlorobenzene in the soil samples is 0.316 μg g-1. It can also be extended to be applied in extraction evaporative organics matter.
