-
摘要: 用气相色谱的氢火焰离子化检测器及熔融石英毛细管柱测定在煤油体系中痕量的DBP(磷酸二丁酯)和MBP(磷酸一丁酯)。DBP和MBP的测定范围是从(1×10~(-5)-1×10~(-4))mol/l,给出了分离条件与校正系数和结果,这是一种方便、快速和可靠的分析煤油体系中DBP和MBP的分析方法。Abstract: Trace amount of DBP and MBP in TBP-kerosene system is determined by gas chromatography with FID (Flame Ionization Detector) and fused silica capillary column. The range for determination of DBP and MBP is from 1×10-5mol/l to 1×10-4mol/l. The separation conditions, correction factor and results are given. This is a convenient, rapid and reliable analytical method for DBP and MBP in TBP-kerosene system
