A novel analytical approach has been developed and evaluated for the quantitative analysis of 15 organophorous pesticides residues in camellia oils. The proposed methodology is based on acetonitrile/water (3:1, V/V) extraction, followed by matrix solid-phase dispersion, using aminopropyl as dispersant material. Then gas chromatography-flame photometric detection was applied for the pesticide residue analysis. The optimal sorbent quantity was studied. The results demonstrated that the method achieved acceptable quantitative recoveries of 71.5%-104.2% with relative standard deviations <19%, and the method limit of detection at or below the regulatory maximum residue limits for the pesticides were achieved.
建立并评价了一种新的分析方法，用于定量分析茶油中的 15 种有机磷农药残留。该方法基于乙腈/水（3:1，V/V）提取，然后采用氨基丙基作为分散剂的基质固相分散，最后应用气相色谱-火焰光度检测进行农药残留分析。研究了最佳吸附剂用量。结果表明，该方法的定量回收率为 71.5%-104.2%，相对标准偏差<19%，方法检出限达到或低于农药的法定最大残留限量。
