Abstract
The behavior of phenol in the terrestrial environment is strongly regulated by its reaction with soil components. We report here on the uptake of phenol by soil minerals (goethite, kaolinite, and montmorillonite) and by organics that may occur naturally in or be added to soil (two lignins, chitin, cellulose, collagen, and activated carbon). Our objectives were to determine the energetics and capacity for their uptake of phenol using batch equilibration, calorimetry, and CPMAS 13 C NMR and to evaluate the relation of organic carbon referenced sorption coefficient (K oc ) with the polarity of biopolymers. The biopolymers sorbed 2-45-fold more phenol than did the minerals
