7 - Sodium Acetate Leach

A 0.75 g sample of -60 mesh B soil horizon material is leached in Sodium Acetate matrix at 30°C for 1 hour. Two controls for every 49 samples are leached in the same procedure.

 

The solutions are analyzed on a Perkin Elmer ELAN 6000, 6100 or 9000 ICP/MS.  One matrix blank is analyzed per 49 samples. Two controls are run at the beginning and end of the group of 49 samples. Duplicate samples are leached and run every 10 samples.
