Abstract:A rapid method for speciation and determination of organomercury compounds in biological samples of marine origin using Capillary Electrophoresis (CE) is reported. Organomercurials were extracted from the samples by means of the classical West66 procedure thus giving organomercury- cysteine complexes which can be separated from each other by means of CE resulting in effective speciation. Electrophoretic separation was achieved in an open silica capillary tube at 15-18 kV using a IOChrN sodium borate buffer (pH 8.35). All mercury species were distinctively separated within 12 min. Results are presented for the analysis of real marine samples and reference materials, and compared with those obtained by the GC commonly accepted procedure.
