Standard Test Method for Solvent-Free Membrane Recoverable Oil and Grease by Infrared Determination

Importancia y uso:

5.1 The presence and concentration of oil and grease in domestic and industrial wastewater is of concern to the public because of its deleterious health, environmental, safety, and aesthetic effects.

5.2 Regulations and standards have been established that require monitoring of oil and grease in water and wastewater.4

Note 1: Different oil and grease materials may have different infrared absorptivities. Certain materials, such as synthetic silicone-based or perfluorinated oils, may have absoptivities inconsistent with those of naturally occurring oil and grease materials. Caution should be taken when testing matrices suspected of containing proportions of these materials. In such cases, laboratory spike samples, laboratory check samples, equivalency testing, or combinations thereof, using these materials in question may be appropriate.
