摘要: 汞是重要的污染元素之一,尤以有机汞的毒性更大.早期的研究工作,大多采用气相色谱法,它要求试样必须具有挥发性和热稳定性,因而在应用上受到一定限制.

关键词: 反相高效液相色谱分析, 铋试剂Ⅱ, 有机汞形态分析

Abstract: With precolumn derivatization by Bismuthiol Ⅱ , MeHg+, EtHg+ and PhHg+ were quantitatively separated and determined by RP-HPLCon a Shimadzu CLC-C8 column.Abu-tanol-methanol-water mixture was used as the mobile phase, and malic acid was chosen as an auxiliary complexant.The detection limits are 1.4 ng(MeHg+), 1.0 ng(EtHg+) and 2.5 ng (PhHg+), respectively.The method was applied to speciation analysis of organomercury in environmental water.

Key words: RP-HPLC, Bismuthiol Ⅱ, Speciation analysis of organomercury
