Standard Practice for Acid-Extraction of Elements from Sediments Using Closed Vessel Microwave Heating

Importancia y uso:

4.1 Partial extraction of soils and sediments can provide information on the availability of elements to leeching, water quality changes, or other site conditions.

4.2 Rapid heating, in combination with temperatures in excess of the atmospheric boiling point of nitric acid, reduces sample preparation or reaction times.

4.3 Little or no acids are lost to boiling or evaporation in the closed digestion vessel so additional portions of acid may not be required. Increased blank corrections from trace impurities in acid are minimized.
