High-purity FePO4 was purified from iron-based phosphating slag as raw material, and FePO4@SAPO-34 was synthesized by hydrothermal crystallization method under the action of templating agent-diethylamine. The synth esized FePO4@SAPO-34 samples were characterized by x-ray diffraction (XRD), scanning electron microscopy (SE M) and Fourier transform infrared spectroscopy (FT-IR). The effects of different crystallization time on the morpholo gy and crystallization of FePO4@SAPO-34 crystals were investigated. The removal of heavy metal ion wastewater by low-cost FePO4@SAPO-34 was investigated. The experimental results show that when the reaction time is 180 °C an d the reaction time is 72h, the crystallization of FePO4@SAPO-34 is the best. When the dosage is 0.6g, the removal efficiency of heavy metal ions is the highest.
