GAS CHROMATOGRAPHIC DETERMINATION OF TRACE AMOUNT OF DBP AND MBP IN TBP-KEROSENE SYSTEM

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
