Description

ASTM D4503-86-Reapproved2003

Historical Standard: Standard Practice for Dissolution of Solid Waste by Lithium Metaborate Fusion

ASTM D4503

Scope

1.1 This practice covers the drying, ashing, and solubilization of solid waste using a lithium metaborate (LiBO₂) fusion for the subsequent determination of inorganic constituents by argon plasma emission spectroscopy or atomic absorption spectroscopy.

1.2 The following elements may be solubilized by this practice:

1.3 This practice has been used successfully with a bauxite ore and a neutralized metal treatment sludge. The practice may be applicable to other elements not listed above. Some metals, such as cadmium and zinc, may volatilize from some samples during the drying, ashing, or fusion steps. The analyst is responsible for determining whether the practice is applicable to the solid waste being tested.

1.4 This practice is intended for the solubilization of nonvolatile inorganic constituents in solid waste. The LiBO2 fusion is appropriate for a silicate matrix or acid resistant samples.

1.5 This standard does not purport to address all of the safety problems 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. For specific hazard statements see Section 7.
