METHOD 3015
MICROWAVE ASSISTED ACID DIGESTION OF AQUEOUS SAMPLES AND EXTRACTS
1.0SCOPE AND APPLICATION
1.1This digestion procedure is used for the preparation of aqueous samples, mobility-procedure extracts, and wastes that contain suspended solids for analysis, by flame atomic absorption spectroscopy (FLAA), graphite furnace absorption spectroscopy (GFAA), inductively coupled argon plasma spectroscopy (ICP), or inductively coupled argon plasma mass spectrometry (ICP-MS).
The procedure is a hot acid leach for determining available metals.
Due to the rapid advances in microwave technology, consult your manufacturer's recommended instructions for guidance on their microwave digestion system and refer to the SW-846 "DISCLAIMER" when conducting analyses using Method 3015. 1.2
Samples prepared by Method 3015 using nitric acid digestion may be analyzed by FLAA, GFAA, ICP-AES, or ICP-MS for the following:
Aluminum Lead
Antimony Magnesium
Arsenic* Manganese
Barium Molybdenum
Beryllium Nickel
Cadmium Potassium
Calcium Selenium*
Chromium Silver
Cobalt Sodium
*Cannot be analyzed by FLAA
