Abstract:
It discloses a method for preparing a magnesium-aluminum hydrotalcite-loaded nano zero-valent iron material for specifically removing perfluorooctanoic acid in a water environment and an optimized process for removing perfluorooctanoic acid thereby, and relates to the technical field of removing persistent organic pollutants in water using adsorption method and oxidation-reduction method and, in particular, to a composite material prepared by loading a nano zero-valent iron on magnesium-aluminum hydrotalcite using liquid phase reduction method.
