ABSTRACT
A method for the determination of seven bisphenol compounds in disposable tableware was established based on solid-phase extraction-supercritical fluid chromatography. The effects of extraction conditions and purification conditions on the extraction efficiency of bisphenol from disposable tableware were investigated. Disposable tableware samples were extracted by ultrasonic with acetone as a solvent, purified by HLB solid-phase extraction column, analyzed by supercritical fluid chromatography, and quantified by external standard method. The actual samples of disposable tableware of different materials were analyzed, and it was found that there were residues of BPA, BPF, and BADGE with a content of 0.45-4.10 mg/kg. The method was green and efficient, which was suitable for the determination of bisphenol compounds in disposable tableware.
