- Description
- Despite previous research focused on the global distribution, long-term fate and the bioaccumulation of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), knowledge related to the development of different remediation options is largely lacking for these compounds (Kupryianchyk et al. in press). Clay minerals including fibrous palygorskite have a number of potential applications in the treatment of emerging environmental contaminants. One novel approach for improving the contaminant-removal efficiency of clay minerals has been the development of organoclays which significantly add to the remediation performance of the material. Similar to lamellar clay minerals, palygorskite can also serve as an effective host of organic surfactants. However, information on removal performance of contaminants having emerging concerns (e.g., perfluorooctane sulfonate and perfluorooctanoic acid) by organopalygorskite is scarce in the literature. The aim of this study is to assess the adsorption of PFOS and PFOA by an organically modified palygorskite under environmental conditions.
