摘要：

A reversed-phase high-performance liquid chromatographic method has been developed for the determination of organic and inorganic mercury species as pyrrolidinedithiocarbamic complexes using electrochemical detection. These complexes were prepared off-line and separated using as mobile phase a mixture of methanol-water (75:25) containing KNO3 as supporting electrolyte. The organomercury complexes were detected in both amperometric and coulometric mode, at +1.15 V and +0.90 V respectively. The detection limits ranged from 0.16 ng to 2.8 ng.
