项目摘要
Aromatic hydrocarbons are widely concerned because of their abundant geochemical information contained in their molecular isotopic composition. However, due to its complex composition, it is easy to be interfered by co-elution and UCM, and it is difficult to obtain reliable isotope data. The QuEChERS method is a novel pretreatment technique for extraction and purification of multiple components based on the principle of solid phase dispersion extraction. Therefore, this project intends to develop QuEChERS method for oil and gas geological sample pretreatment, combined with the characteristics of oil and gas geological samples, based on the theory within the target component and co-extractions are differences in log Kow and polarity, this technology is systematic researched and optimized, the best extraction agent and purified agent are determined, different factors on extraction efficiency, purification results and isotope fractionation effect are investigated, and QuEChERS technology suitable for isotope analysis of oil and gas geological aromatic is established. On this basis, the new method is compared with the traditional method for different types of samples, and is validated and perfect to realize the aromatics separation and purification, and to meet the isotopic determination requirements. The purpose is to establish the QuEChERS pretreatment technique suitable for the compound specific isotope analysis of aromatic hydrocarbon of oil and gas geological samples, to provide new technical method for the further study of aromatic isotopes, and to lay a foundation for the comprehensive application of the technique in the field of oil and gas geology.
芳烃同位素组成蕴藏丰富地球化学信息,是油气地球化学重要研究领域。但由于其组成复杂,易受共溢出物和UCM干扰,难以获得可靠的单体同位素数据,针对芳烃的分离净化技术是制约其应用的关键技术难题。QuEChERS方法是基于固相分散萃取原理进行多组分提取分离净化的新型前处理技术,本项目拟采用该方法进行油气地质样品芳烃提取净化,并结合地质样品组成特点对该方法系统研究。根据目标组分与其他组分正辛醇-水分配系数和极性的差异性,筛选合适的萃取剂及净化剂,查明其中不同因素对芳烃组分提取率、净化结果和同位素分馏等影响,优选最佳方案,在此基础上对不同类型样品进行新方法和传统方法对比研究,验证及完善新方法,实现芳烃分离净化,满足其同位素测定要求。旨在建立适合油气地质样品芳烃单体同位素分析的QuEChERS前处理技术,为进一步开展芳烃同位素研究提供新的技术手段,并为该技术全面应用于油气地质领域奠定基础。
