摘要

汞是油气中最重要的毒性物质之一,油气燃烧后,汞会进入大气造成环境污染。随着分析技术的不断发展,对汞在油气中的存在形式有了进一步的认识。准确地确定油气中总汞和汞化合物物种需要熟练的采样方法和严格的分析技术,因为利用常规的分析技术很难检测到油气中的某些汞化合物。目前,已有关于石油中不同汞化合物的报道,但数值变化范围很大,对于二甲基汞作为人类潜在的危害有了一些认识,其在油气中准确的含量仍有待深入研究,油气中汞及其化合物的含量和相对分布主要与源岩类型和地质背景有关。

Abstract

Mercury is one of the most important toxic elements in oil and gases.Owing to the high volatize feature Hg tend to dispose into the air during combustion and therefore it results in the environmental pollution. The understanding of various chemical forms of mercury in hydrocarbon matrices has evolved due to technical advances.Accurate determinations of total mercury and speciation of mercury compounds in oil and gases depend on sophisticated sampling techniques and rigorous analytical procedures.
