Abstract
The possibility of capturing and detg. As species in different phys. states by the title method was demonstrated with the use of dust, As2O3, and AsH3. Calibration with aq. solns. works well with As2O3 and dust but not with AsH3. However, AsH3 (and other highly volatile compds.) represent a significant fraction of the total As only near specific sources of pollution.File in questo prodotto:
