Standard Test Method for Chlorophenoxy Acid Herbicides in Waste Using HPLC (Withdrawn 2019)

Scope

1.1 This test method covers the analysis of 2,4-dichlorophenoxyacetic acid (2,4-D), 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), and 2,4,5-trichlorophenoxypropionic acid (silvex) in liquids and solids, using high performance liquid chromatography with an ultraviolet detector (HPLC/UV). This test method is applicable for a concentration range from approximately 50 to 1000 ppm. This range takes into consideration the sample preparation and dilutions outlined in Section 10. Lower detection levels can be obtained by using larger sample sizes, smaller total final volumes, or with the use of in-line or solid phase extraction, concentration, or cleanup, or combinations thereof.

1.2 The chlorophenoxy herbicides may be present as a variety of salts or esters, which are converted to, analyzed, and reported as their respective acids.

1.3 This test method is applicable to liquid and solid waste and waste extract matrices including aqueous, oil, spent solvent, soil, ash, leachates, etc.

1.4 This test method may be applicable to other phenoxy acid herbicides.

1.5 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. See Section 7 and 10.3.1 for specific precautionary statements.

Significance and Use

4.1 Phenoxy acid herbicides are used extensively for weed control. Esters and salts of 2,4-D, 2,4,5-T, and Silvex have been used for agricultural crop and lawn care.
