Scope: This standard specifies the terms and definitions, test substance information, method overview, test preparation, test, quality control, data and reports for estimating the adsorption coefficient of chemicals in soil and sludge by high performance liquid chromatography (HPLC). This standard applies to substances with stable chemical properties during the test, especially to substances that are difficult to test by other methods, such as: volatile substances, substances whose concentration cannot be analyzed and tested due to poor water solubility, and substances that have a strong affinity for adsorption test utensils It is also suitable for mixture systems containing incompletely separated elution bands (the 1gK of the test mixture should give its upper and lower limits). The adsorption coefficient (1gKoc) applicable to this standard ranges from 1.5 to 5.0. This standard does not apply to substances that can react with the stationary phase or mobile phase of high performance liquid chromatography, substances that can interact with certain inorganic substances in a special way (for example, form complexes with clay mineral bases) and surface active substances. Agents, inorganic substances, medium strong acids and bases.
