报道了固相微萃取-电化学法测定痕量汞的方法。SPME/EC纤维由具有10 µm金涂层的碳钢丝制成。采用电化学方法从水溶液中提取汞离子，用专用解吸系统解吸，然后用离子阱GC-MS检测。检测到水溶液中的汞离子和气体中的汞蒸气。对无机汞和有机汞化合物进行了区分。
Solid-phase microextraction combined with electrochemistry (SPME/EC) for trace level mercury determination is reported. An SPME/EC fibre was made of a carbon steel wire with a 10 µm gold coating. Mercury(II) ions were electrochemically extracted from aqueous solution, and desorbed with a dedicated desorption system, then detected by ion-trap GC–MS. Mercury(II) ions in aqueous solution, and mercury vapour in gas, were detected. Inorganic mercury and organomercury compounds were differentiated.
