Abstract

This invention discloses a distillation packing material for treating tritium-containing wastewater and its preparation method. The method includes the steps of cleaning and drying a metal wire mesh packing material in an ultrasonic cleaner to obtain packing material A; immersing packing material A in a dilute HNO3 solution for corrosion modification to obtain packing material B; mixing a metal salt and an organic ligand in a solvent to obtain a loading solution C; and adding packing material B to the loading solution C and heating it in a high-pressure-Telflon reactor in a muffle furnace to obtain distillation packing material X. The distillation packing material of this invention, by modifying the metal packing material to improve its hydrophilicity, can better adsorb and retain water molecules, allowing them to be better distributed and flowed within the column, which is beneficial for improving mass and heat transfer efficiency. Furthermore, loading metal-organic framework materials (MOFs) capable of exchanging with hydrogen isotopes onto the modified metal packing material improves the separation and purification effect during the distillation process of treating tritium-containing wastewater.
