Abstract
In order to simultaneous extraction and determine of p-nonylphenol (NP), p-nonylphenol monoethoxylate (NP1EO) and p-nonylphenol diethoxylate (NP2EO) from sediment samples, the accelerated solvent extraction parameters were optimized in terms of extracting temperature, extracting pressure, extracting cycle and extracting solvent. The phenolic compounds extracted were silyl derivated with bis( trimethylsilyl) -trifluoroacetamide (BSTFA) in the acetone or acetone-dichloromethane mixture ( acetone >= 60%). The best extracting: 120 degrees C, 8.33 MPa ( 1200 psi), two cycles and dichloromethane. Average extraction recovery of spiked analytes ranged from 89.3 to 95.7% with. low RSD of 2.3% - 13.4%. Method detection limits for the determination of NP,NP1E0 and NP2E0 are 10, 30, 35 ng/g dw, respectively.
