Flourine-Induced Chemiluminescence Detection of Biologically Methylated Tellurium, Selenium, and Sulfur Compounds and Methyldithiocarbhydrazide as a Formaldehyde Derivatization Reagent

摘要

Part I of the report details a successful method of detecting biologically methylated selenium and tellurium compounds released by microorganisms grown in the laboratory. These reduced, volatile molecules are part of the natural cycling of elements between the biosphere and the atmosphere. Also described is the sensitive detection of phosphine and alkylated phosphine compounds that may play a role in the atmospheric phosphorus cycle. Part II describes an attempt at the development of a method to collect, derivatize, and quantify formaldehyde, a trace constituent found in both polluted and non-polluted environments. Both of these techniques center around the use of a sensitive, selective analytical instrument for gas chromatography, the F2-induced chemiluminescence detector, which up until this time has not been applied to these compounds nor to any derivatization technique.
