Historical Standard: ASTM D2373-85(1999) Standard Test Method for Determination of Cobalt in Paint Driers by EDTA Method
SUPERSEDED (see Active link, below)
ASTM D2373
1. Scope
1.1 This test method covers a titrimetric determination of cobalt in liquid paint driers that can be dissolved in glacial acetic acid and utilizes the disodium salt of ethylenediaminetetraacetic acid dihydrate (EDTA).
1.2 This test method is not applicable to drier blends. If driers other than cobalt are present, they may interfere by reacting with EDTA under the conditions used for analysis.
1.3 All cations that can be titrated with EDTA in alkaline media interfere and must not be present in the sample.
1.4 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.
