Leach characterization of cement containing polychlorinated organic compounds under static and dynamic water conditions
The effects of polychlorinated biphenyls (PCBs) on the physical properties of a cement matrix and the leachability under static and dynamic water conditions have been studied. Different analytical techniques are reported for the extraction and analysis of PCBs from water samples, the most common being the liquid-liquid extraction method. LC-18 (6ml, 0.5 g), a cartridge packed with octadecyldimethylsilyl phase, has been used for trace enrichment of PCBs from water. The low percentage release of PCBs under both static and flowing water conditions indicate that PCBs are well contained in a cement matrix. This is confirmed by the leachability index values for individual PCB congeners (dynamic water leaching) which range from 13.29 to 14.34 following a release order 101 138 153 180, which seems to be dependent on solubility limits and different adsorption behaviour of each congener, respectively. From the results of the present investigations it could be concluded that other PCB congeners will have similar effects on the cement matrix.
