History of Research and Developments, and Latest Trends in Decomposition Techniques for PFOS and PFOA in Water

Abstract

The target of the review article is to discuss the state-of-the art technologies applicable to the remediation of PFOA and PFOS contamination of the water environment. Firstly, we summarize the pollution of the environment with PFOA and PFOS to clarify the treatment technologies required in the field. Then we outline the principle and effectiveness of the existing treatment technology for PFOA and PFOS, with more focus on decomposition rather than sequestering techniques. The difficulties encountered in the decomposition of these substances are explained from their chemical structure and properties. Finally, combinations of feasible treatment technologies, i. e., treatment train, to PFOA and PFOS in water are discussed.
