摘要
烷基汞是汞在自然界中的一种有机物形态,广泛存在于大气环境、水环境及土壤环境中。文章主要介绍了如何使用巯基棉提取水中的烷基汞、并用GC-MS测定烷基汞。在保证测试结果准确的前提下,改进了洗脱速率和洗脱装置,本法的检出限为:甲基汞(MMC)10 ng/L,乙基汞(EMC)10 ng/L。
Alkyl mercury is an organic form of mercury in the nature and widely exists in the atmosphere, water and soil. The paper mainly introduced how to extract alkyl mercury in water by sulfhydryl cotton and determine it by GC-MS. Under the premises that the correctness of the test result is well ensured, the elution rate and elution device has been improved. The determination limit of this method is： Methyl mercury （MMC）, 10 ng/L; Ethyl mercury （EMC）, 10 ng/L.
