Determination of the adsorption-coefficients of organic substances on sewage sludges

摘要

The sorption capacities of sewage sludges were tested with a set of organic substances. The influence of test conditions on the results was investigated. It could be shown tat the sorption capacity as related to the organic carbon content of sludges (K_oc-values) is comparable to those of agricultural top soils Necessary and useful modifications to the OCECD TG 106 adsorption - desorption in soils are described to adapt the guideline for testing of sludges.
