| 摘 要： | 为了测定使用甲醇燃料的发动机排气里的亚硝酸甲酯(MeONO)和硝酸甲酯(MeONO_2)含量,建立了色谱分析方法。本方法的最小检测限MeONO为20ppb,MeONO_2为50ppb。对自制的MeONO和MeONO_2进行了质谱鉴定,并对所制备的一定浓度的样品进行了稳定性考察。应用本方法测定了甲醇机排气中的MeONO含量为5ppm—250ppm,MeONO_2含量为<50ppb。

| Abstract: | A GC analytical method for determination of methyl nitrite and methyl nitrate concentrations in exhauset gas from the engine fuelled with methanol has been established. The minimal concentrations of MeONO and Me-ONO2 determined by this method are 20ppb and 50ppb respectively. The prepared MeONO and MeONO2 were identified with mass-spectrometry and stability of the samples of these substances were observed with gas chrcma-tography. The concentrations of the pollutants exhausted from Santana M100 engine were determined in 5-250 ppm for MeONO and less than 50ppb for MeONO2. |
