SEPARATION TECHNIQUES IN SPECIATION ANALYSIS FOR ORGANOMETALLIC SPECIES

A comprehensive review of the state-of-the-art of the separation of va rious organically-bound metals and metalloids for speciation analysis is presented. Recent developments in chromatographic (gas, liquid and supercritical fluid), electrophoretic (free-flow and gel) and fraction ation techniques are discussed, followed by a survey of pertinent appl ications to speciation analysis for organometals and metalloids. The r equired sample characteristics for a given separation technique are sp ecified and appropriate derivatization procedures are characterized. M ethods applicable to the speciation of organic species of a particular element in various matrices are critically evaluated.
