CONTRIBUTION OF NEUTRON ACTIVATION ANALYSIS AND RADIOANALYTICAL TECHNIQUES TO TRACE ELEMENT SPECIATION IN ENVIRONMENTAL ANALYSIS
The feasibility of the NAA in contributing to trace element speciation in environmental and biological samples is shown by a few selected applications. They are: (i) the determination of different species of vanadium, arsenic and selenium in freshwater. The pre-irradiation treatments in which the different chemical species are selectively isolated are critically evaluated. Problems arising from possible contaminations or losses and from blanks are discussed; (ii) the use of NAA in metallobiochemical speciation once biochemical methods of cellular fractionation for the isolation of metallobiocomplexes are developed. Examples concern the biochemical speciation of vanadium in human blood and the development of a method for speciation of inorganic and organic compounds in biological samples. The use of radioanalytical techniques in developing the separation procedures of different trace metal chemical and biochemical species is also briefly discussed.
