Abstract

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
