| 摘 要： | 建立了气相色谱-质谱(GC-MS)分段选择离子监测(SIM)模式分析同时测定橡皮擦中22种邻苯二甲酸酯(PAEs)增塑剂含量的方法。该方法具有良好线性,相关系数R均大于0.999,检测限在1.3 mg/kg～128.9 mg/kg之间,平均回收率在70.2%～105.6%,相对标准偏差在2.57%～9.88%之间。通过该方法对国内橡皮擦中PAEs增塑剂进行检测,实际样品均检出邻苯二甲酸二(2-乙基)己酯(DEHP),含量最高达32.5%。

| Abstract: | A method for the simultaneous determination of 22 phthalate acid esters （PAEs） plasticizers in erasers by gas chromatography-mass spectrometry （GC-MS） with subsection S1M mode was developed. The correlation coefficients （ R ） of 22 PAEs were over 0.999 with detection limits from 1.3 mg/kg to 128.9 mg/kg. The average recoveries of 22 PAEs in erasers were ranged from 70.2 % to 105.6 %. Iu addition, the relative standard deviations（ RSDs ） were in the range of 2.57 % - 9.88 %. The study investigated the level of phthalate acid esters plasticizers in erasers by this method, di-（ 2-ethylhexyl ） phthalale （ DEHP ） was ound in all real samples, the maximum content of DEHP was 32.5 %. |
