Recovery of phenols from water by extraction freezing

A procedure was developed for the recovery of phenol from aqueous solutions into acetonitrile using extraction freezing. Experimental results and the revealed regularities were discussed in the context of the proposed theoretical model. The low temperature used in the sample preparation advantageously distinguishes this procedure from the conventional versions of the extraction recovery of organic compounds from water. Moreover, the procedure does not require special glassware or expendable materials.
