ASTM D3683-04

Standard Test Method for Trace Elements in Coal and Coke Ash by Atomic Absorption

SIGNIFICANCE AND USE
Many trace elements occur in coal, primarily as a part of the mineral matter but may also be associated with the organic matrix. Concern over release of certain trace elements to the environment as a result of coal utilization has made the determination of these elements an increasingly important aspect of coal analysis.
When coal ash is prepared in accordance with this test method, the eight elements listed in 1.1 are quantitatively retained in the ash and are representative of concentrations in the coal. Concentrations of these and other elements in power plant ash, industrial process ash, fly ash, and so forth, may or may not be representative of total quantities in the coal.
SCOPE
1.1 This test method describes a procedure for the determination of beryllium, chromium, copper, manganese, nickel, lead, vanadium, and zinc in coal ash or coke ash. Note 1Although not included, this test method can be applicable to the determination of other trace elements, for example, cadmium.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.2 The values stated in SI units (IEEE/ASTM SI 10) should be regarded as the standard.
