摘要
对液化石油气中硫化物的分析方法进行了评述。总硫测定多采用氧化微库仑法 ,灯法等。形态硫分析多采用气相色谱与硫选择性检测器结合的方法 ,这些检测器有火焰光度检测器 (FPD) ,原子发射检测器 (AED) ,硫化学发光检测器 (SCD)和脉冲火焰光度检测器 (PFPD)等。其中硫化学发光检测器能较好地检测液化石油气中的各种形态硫化物。此外 ,液相色谱法 ,燃烧 离子色谱法 。
Analytical methods for sulfur compounds in liquified petroleum gas are reviewed. The total sulfur is generally determined by oxidization microcoulometry or lamp method. The sulfur compounds are mainly determined by gas chromatography combined with sulfur selective detectors (flame photometric detector, atomic emission detector, sulfur chemiluminescence detector and pulsed flame photometric detector). The pulsed flame photometric detector is suitable for different types of sulfur compounds in liquified petroleum gas. Other methods, such as high performance liquid chromatography, combustion ion chromatography, polarography and nuclear magnetic resomance, can also be used.
