Diagnostic Assay of Trace Mercury in Muscle Cells.

: An electrochemical diagnostic assay of a trace mercury was performed using stripping voltammetry, cyclic voltammetry and chronoamperometry. Three graphite pencil electrode systems were used as the working, auxiliary and reference electrodes. Fluorine immobilization was performed on the working electrode to improve the sensitive low detection limit. Clean seawater was used instead of an expensive electrolyte such as buffer solution, acid or base solution. The working ranges are better sensitive then observed for analogous method. The result was applied to the muscle cell of an earthworm that lived in soil contaminated with trace mercury.
