Abstract
A description is given of a method for the determination of mercury in
rocks; its main feature is the rapid separation of mercury. The
irradiated sample is heated in an induction furnace, and the mercury
vapours expelled are adsorbed on filterpaper impregnated with selenium.
The yield of separation is 90%, and the total time taken by the
procedure is about 6 minutes. This method has been applied for the
determination of mercury in 8 USGS standard rocks; the results obtained
indicate a precision of +-10-20%. The homogeneity of the standard
samples is discussed. Samples were irradiated for 12 hours in the
central thimble of the TRIGA MARK II reactor of the Reactor Laboratory
at a thermal flux of 1013cm-2s-1. After decay for 1-2 days of short-lived isotopes the separation of mercury was performed. (F.Gy.)
