| 摘 要： | 一、二、三硝基甲苯(简称MNT、DNT和TNT)共有15个异构体.分离这些异构体文献中虽有一些报道1-9],但均不太完善.我们曾用液晶填充柱分离和测定MNT的三个异构体10];用OV-225填充柱分离DNT的六个异构体11];用OV-25和OV-210混合固定液填充柱分离TNT六个异构体12].

| Abstract: | A new method is described for the separation of 15 isomers of mono-, di- and trinitrotoluene on a shorter glass capillary column coated with OV-225 as stationary phase. Relative retention ratio and resolution of these isomers were determined on this column, and it shows that all the isomers can be separated and determined in less than 12 mins.Acolumn 9.2m long is suitable for determination of all the isomers and a column 5.8m long for rapid separation of the isomers of TNT at 195℃ within 10 min. |
