Functionalized sponge-based wastewater dephosphorization adsorbent and preparation method thereof

The invention discloses a functional sponge-based wastewater dephosphorization adsorbent and a preparation method thereof, and belongs to the field of water pollution control, and the preparation materials of the dephosphorization adsorbent comprise M IL-101 particles and a melamine sponge carrier; the preparation method of the phosphorus removal adsorbent specifically comprises the following steps: pressing melamine sponge into a coating solution for multiple times; drying the sponge at the temperature of 80-100 DEG C for 6-12 hours, and then washing with methanol for multiple times; and drying at 60-80 DEG C, cooling, and collecting the sample. The preparation method of the coating solution comprises the following steps: preparing MIL-101 particles, adding the weighed MIL-101 particles into a solvent, carrying out ultrasonic treatment for 1-30min, then adding a chitosan solution, and carrying out ultrasonic treatment for 1-30min to obtain the uniform coating solution. According to the method for rapidly ads
