| Abstract: |
| Methods for the determination of typical organic flotation reagent（α - terpineol）in water and soil samples were respectively established using solid phase extraction（SPE） purification and gas chromatography/mass spectrometry（GC-MS）. Chromatographic separation of the analyte was performed using DB-5 MS, and its quantitative analysis was performed using electron bombardment（EI）- selected ion monitoring（SIM）and matrix-matched calibrations. Both water and soil samples were extracted with dichloromethane. For water sample, pH and salinity were adjusted to 7.5 and 0.5%, respectively, followed by three times of liquid-liquid extraction using dichloromethane as extractant. For soil sample, dichloromethane was used for oscillatory extraction twice. The extract was evaporated to dryness and then diluted to 1 mL with methanol as the extract. The extracts of water and soil samples were purified by solid phase extraction using a C18 cartridge. Under the optimal extraction conditions described above, the analyte showed a good linear relationship in the concentration range of 0.1~5 mg·L-1（R2≥0.998）. Its limit of detection（LOD）was determined as 0.027 mg·L-1 to 0.041 mg·L-1（water samples）and 0.009 mg·kg-1 to 0.054 mg·kg-1（soil samples）, respectively. Its recoveries of spiked samples at different concentrations （1, 2, 5 mg·L-1 or 1, 2, 5 mg·kg-1）were 91.5% to 112% [Relative standard deviation（RSD）<15%, water samples] and 67% to 114% （RSD<15%, soil samples）, respectively. |
