The determination of organomercurials in surface waters containing high organic loads
- Florida Dept. of Environmental Protection, Tallahassee, FL (United States). Chemistry Section
A method to measure trace quantities of methyl mercuric chloride and other organomercurials in surface waters containing high organic loads has been developed. Since organomercurials are usually present at ultra trace levels (0.02 to 0.2 ng/L) in surface waters, sample pre concentration is often necessary. This paper outlines the use of solid phase extraction to achieve the desired pre concentration. The compounds are then separated using gas chromatography and detected using an atomic fluorescence detector. Unlike the conventional approach which employs ethylation, there is no need to derivative the organomercurials to their more volatile ethylated analogs, and direct injection of the SPE extract onto a column is possible. Moreover this technique lends itself to a limited amount of automation, and higher throughput. Results from the analysis of surface waters from the Florida Everglades will be presented.
