The remediation need for polychlorinated biphenyls (PCBs) still remains long after their production ban around the world. The development of low cost methods is highly desirable, especially for developing countries, in response to the Stockholm Convention. In this study, the dechorination of a ubiquitously present PCB congener was studied using a catalytic hydro-dechlorination (HDC) method in low temperatures up to ~ 77°C and was able to achieve near 100% dechlorination in six hours. Results indicated that the HDC process can be performed under mild temperatures and atmospheric conditions and can be a potential solution to real world PCB contamination issues.
