Chemical vapor generation of noble metals for analytical spectrometry.
As is apparent from the literature devoted to the analytical atomic spectrometry, chemical vapor generation (CVG) of noble metals by reaction with tetrahydroborate in acidic media may enhance the introduction of these elements into different atomic spectrometric sources. Recent developments in the CVG of noble metals species by reaction with tetrahydroborate in acidic medium are surveyed. Different aspects of this novel technique are discussed, including type of instrumentation used for the reaction, separation and transport of the species, effect of chemical and physical factors, identification of the species, and the efficiency of the process. Limitations and future prospects of the CVG technique are discussed.
