| Abstract: | The study aimed at determining phenols in water by using solid-phase extraction （SPE） coupled with high performance liquid chromatograph （HPLC） Discussion on the influence factors of concentrating seven phenols in water by using SPE through the orthogonal experiment and verification experiment, The optimized solid-phase extraction conditions are Oasis HLB solid-phase extraction column, 5 mL/min loading speed, elution solvent is tetrahydrofuran, the elution volume is 2 mL, 2 times ofelution. The method has high recovery, simple operation, less solvent consumption characteristics. |
