| Research Abstract |
In this study, both the removal of anionic perfluorosurfactants (PFS) from those solutions by coprecipitation of Mg-Al layered double hydroxide (LDH) and the subsequent thermal decomposition of PFS in the LDH interlayer have quantitatively been investigated. As the results, PFS anions were highly removed as guest by intercalation in the LDH precipitation process and PFS anions of the LDH precipitate were decomposed at lower temperatures in the thermal decomposition process, because of the catalytic action by metal ions of the LDH host layer.
