A Review of Recent Advances in Detection and Treatment Technology for Perfluorinated Compounds

Abstract

Perfluorinated compounds (PFCs) are a novel type of environmental pollutant with a specific structure. PFCs have become a global concern due to their environmental persistence and biotoxicity properties. In this paper, we review the hazardous effects, detection technologies, and treatment methods of PFCs. We present the current status of PFCs pollution in water, the atmosphere, soil, and organisms. Moreover, we show that PFCs have toxic effects, such as hepatotoxicity, neurotoxicity, immunotoxicity, endocrine disruption, and reproductive and developmental toxicity. Six sample pretreatment techniques and four assays for PFCs are listed in this paper. This review focuses on the analysis of the treatment methods for PFCs, such as physical adsorption, microbial degradation, photochemical oxidation, electrochemical oxidation, acoustic oxidation, Fenton oxidation, and so on. We systematically analyze the treatment effects, removal mechanisms, and future directions of various technologies to provide support and suggestions for PFCs pollution control technologies.

A Review of Treatment Technologies for Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA) in Water

“…Research of minerals with rich pores and large specific surface area used as adsorbent have been taken for a long time. In spite of the electrostatic attraction, the adsorption of PFOS and PFOA by mineral materials is also characterized by hydrogen bonding force and surface complexation, which together contribute to the excellent effect of mineral materials [41]. Zhao et al [42] researched the adsorption effect of PFOS and PFOA on montmorillonite, kaolinite, and hematite.…”

Determination of Perfluorooctanoic Acid (PFOA) in the Indoor Dust Matter of the Sicily (Italy) Area: Analysis and Exposure Evaluations

“…They are also found in kitchen utensils, like in non-stick coatings [ 12 , 13 , 14 ]. Unfortunately, (C–F) chemical bonds make PFAS very stable and they do not degrade when exposed to heat, acids, or oxidation substances, nor do they degrade naturally [ 15 , 16 ]. Because of these strong properties, PFAS are classified as highly persistent pollutants [ 17 ].…”
