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
