Efficient PVG was accomplished in a flow-through photoreactor using formic acid-based reaction media. Generated volatile products (metal carbonyls) were directed by an argon carrier gas to a gas-liquid separator and introduced into an inductively coupled plasma mass spectrometer for detection. Details on optimization of generation conditions and influence of various metal sensitizers (additives) will be presented. Particular attention will be paid to the determination of PVG efficiency, which is the parameter that describes the best overall yield of PVG and is directly reflected in achieved sensitivity. The accuracy and feasibility of this sensitive methodology (limits of detection in pg ml–1) will be demonstrated by the results from analyses of
Certified Reference Materials and real samples covering a variety of sample matrices. Mechanistic aspects of PVG of these transition metals will be also pointed out and discussed.Pracoviště Ústav analytické chemie Kontakt Iveta Drobníková, drobnikova@iach.cz, Tel.: 532 290 234 Rok sběru 2022
