摘　　要：四氯化碳作为石油类萃取剂对人体毒害较大,破坏臭氧层,已被联合国环境规划署列入加速淘汰计划。本研究尝试用四氯乙烯替代四氯化碳作为石油类测定萃取剂。结果表明,二者在线性、检出限、精密度、萃取率、加标回收率、质控样品测定方面没有显著差异,该替代方法基本可行。Carbon tetrachloride, an extracting agent to determine petroleum content, is harmful to human health and ozone layer, and therefore has been listed in the phase-out plan by United Nations Environment Programme. In this study, we attempt to use tetrachloroethylene instead of carbon tetrachloride as the extracting agent in determination of petroleum content. The results show that tetrachloroethylene and carbon tetrachloride have no significant difference in linearity, detection limit, precision, extractability, recovery of standard addition and analysis of quality control sample.
