magnesium extraction from dolomite with nitric acid

METHOD 3015A MICROWAVE ASSISTED ACID DIGESTION

1.1 This microwave method is designed to perform extraction using microwave heating with nitric acid (HNO 3), or alternatively, nitric acid and hydrochloric acid (HCl). Since this method is not intended to accomplish total decomposition of the sample, the extracted analyte concentrations may not reflect the total content in the sample.
