中文摘要:
为检测白酒中16种邻苯二甲酸酯类化合物(PAEs)的残留量,建立了液液萃取-气相色谱-质谱法测定白酒中16种邻苯二甲酸酯类化合物。样品采用沸水浴加热先除去乙醇后再用正己烷提取测定,在0.5~8.0 mg/L范围内线性关系良好,相关系数均大于0.997,检出限为0.02~0.05 mg/L,样品加标回收率为82%~106%,结果表明:该方法操作简便、分析快速,能够满足于白酒中16种PAEs的检测分析要求。
英文摘要:
To determine the residual amounts of 16 Phthalic Acid in spirit, a liquid-liquid extraction combined with gas chromatography/mass spectrometry was established. The results showed that linearity of response over 16 phthalic acid esters was good from 0.5 to 8.0 mg/L with higher correlation coefficients(>0.997).The limits of detection were from 0.02 to 0.05 mg/L, in addition, the relative standard deviations(RSDs) were in the range of 0.7%~2.8%. Spike recoveries ranged from 82% to 106% for all samples in same analysis condition. The conclusion indicated that this developed method is simple and quick response for the determination of 16 Phthalic Acid Esters in wine.
