GC-PFPD法分析1-丁烯碳四原料中的微量硫化合物

摘要

利用毛细管色谱柱、脉冲火焰光度检测器及各种形态硫的渗透管,建立了对中石化广州分公司MTBE联产丁烯-1所需的炼厂碳四中的微量有机硫化物的分析方法。此方法可以准确定量含量低至84μg/kg的H2S、44μg/kg的COS和68μg/kg的MeSH。该方法具有操作简便、灵敏度高等优点,适于炼厂碳四原料中微量硫化物的分析测定。%The use of capillary column,pulsed flame photometric detector and the sulfide permeation tube,established a Guangzhou branch of Sinopec MTBE required cogeneration refinery 1-butene plant carbon in four of the analysis of trace organic sulfide method.This method was an accurate quantitative analysis can be as low as 84 μg/kg content of H2S,44μg/kg content of COS,and 68 μg/kg content of MeSH.The method was simple,high sensitivity,suitable for determining the morphology of trace sulfur compounds and detecting the composition trace sulfur compounds.
