Analytical Applications of Volatile Metal Derivatives

V apor generation is a widespread method used for the determ inatio n of m etals, metalloids, and organometallic compounds.Contrary to common belief, a signi cant number of metal(oid)s form volatile species, m any of which occur in nature.Vapor generation is a process wherein nonvolatile (usually ionic-metallic or organom etallic) compounds form volatile or semivolatile species through chemical, physical, or biological processes that may result in their transfer from a condensed phase to the gas phase.It is now well known that numerous volatile and semivolatile metal compounds are present in our environment as a consequence of both anthropogenic and natural processes.For example, m etal hydrides can be formed in m any environm ental settings where reducing conditions prevail.Donard 1 noted release of tin hydride from a model seawater-sediment system more than ten years ago.Several reports have also highlighted detection of metal hydrides
