چکیده
|
This work demonstrated the stir bar sorptive extraction (SBSE) of benzoic acid and sorbic acid followed by HPLC-UV. After optimization, the linearity and limits of detection were in the range of 0.01-7 mg/L and 0.005- 0.006 mg/L, respectively. Acceptable recoveries (>92.3%) with RSDs of less than 5.3% were achieved.
