ASTM E1148-02(2008)

The solubility of organics is a basic physical parameter needed for the prediction of the fate of a chemical in the environment (6).

The ionic strength and organic content of natural waters may cause an apparent decrease or increase from the value obtained in pure water. Data on this can be obtained in the laboratory by modifying the reagent water to simulate natural waters.

1.1 This test method covers procedures for measurement of the solubility of organic compounds in water. Three procedures are described which will work over a variety of solubility ranges. These procedures are not appropriate for compounds that react with water or air at ambient conditions.

1.2 The procedure chosen will depend on the estimated solubility of the compound. This may be obtained from literature values (see Refs 1, 2, 3) by correlation with other parameters (4) or by analogy with the solubility of similar compounds.

1.3 This standard does not purport to address all of the safety problems, 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.
