摘要: AbstractLarge amount of phosphorous is the main factor for eutrophication. Removal orthophosphate and pyrophosphate with CaFe-Cl-LDHs was explored in paper. And aim this paper to investigate different mechanisms removal by CaFe-Cl-LDHs. The results displayed that process precipitation-dissolution between Ca2+ or pyrophosphate, which fitted pseudo-second-order equation well; when not enough, had a competitive advantage over orthophosphate; as concentration increased, precipitate formed . simultaneous on also evaluated provide information treatment domestic industrial wastewaters.
