摘要
为探究煤中锶同位素组成与成煤环境、成煤时代和变质程度的关系,依据不同试剂的提取能力逐级提取煤中不同赋存状态锶,通过不同试剂的对比,提出分离、提取煤中不同赋存状态锶的试剂,建立煤中盐酸提取态、双氧水提取态和残渣态锶分离、同位素测试方法。本研究填补了我国煤中锶同位素研究空白,同时也为今后利用煤中锶同位素组成反映成煤古植物、古气候和古环境等方面信息奠定了基础。
In order to explore the relationship between strontium isotope i n coal and the environment, coal-forming age and metamorphic degree, we extracted the different occurrences of strontium in the coal according to the extraction capacity of different reagents. Through the comparison of different reagents, we proposed respective reagents to extract different occurrences of strontium. We established methods for extraction by hydrochloric acid and by hydrogen peroxide, and separation of residue and strontium isotope test. This research has filled the gaps in the study of strontium isotopes in coal in China, and laid the foundation for the future use of strontium isotope composition in coal to reflect the information of coal-forming ancient plants, paleoclimate and paleoenvironment.
