Analytical Method Metadata
A 1 gram sample was reacted with 6 ml of a mixture of 4 M HNO3 and M HCl in a test-tube overnight at room temperature. After digestion, the test-tube was immersed in a hot water bath at room temperature and brought up to 90oC and held at this temperature for two hours with periodic shaking. The sample solution was then diluted to 20 ml with metal free water and mixed. The element was determined by atomic absorption spectroscopy using an air-acetylene flame.
Background corrections were made.
