New Test Method for Standard Test Method for Determining a Sorption Constant (Koc) for an Organic Chemical in Soil and Sediments
1. Scope
This test method describes a procedure for determining the partitioning of organic chemicals between water and soil or sediment. The goal is to obtain a single value which can be used to predict partitioning under a variety of environmental conditions from the measurement of sorption coefficients for specific solids.
Keywords
equilibrium sorption coefficients; partitioning of organic chemicals; sorption constant (Koc)
Rationale
This is a reinstatement of a withdrawn standard which has regained interest by ASTM members
