中文摘要:
      建立了植物油中TBHQ的中性氧化铝固相萃取-高效液相色谱分析法。分别用TBHQ标准溶液10、25 μg/mL和50 μg/mL进行加标回收率和精密度试验。结果表明:加标回收率在100.0%~103.0%之间,RSD为2.0%~6.0%,说明该方法具有良好的可靠性和重现性。研究表明,该方法操作简便,油脂净化完全,结果准确可靠。
英文摘要:
      A neutral alumina solid phase extraction-high performance liquid chromatography method was established for the analysis of TBHQ in vegetable oil. The standard recovery experiment and precision experiment were conducted using 10, 25 μg/mL and 50 μg/mL TBHQ standard solutions. The results showed that the recovery rate of standard and RSD were 100.0%-103.0% and 2.0%-6.0%,respectively, which showed that the method had good reliability and repeatability. The study indicated that the method had the items of simpleness, complete oil purification, and accurate and reliable result.
