Embodiment 1
[0023] A filler particle comprising diatomaceous earth-based porous ceramics, rare earth chelates, and potassium permanganate.
[0024] Prepared by the following method: 10 parts by weight of diatomite-based porous ceramics are distributed in a rare earth chelate solution, and the mass percent concentration of the rare earth chelate in the rare earth chelate solution is 5%; under the action of ultrasonic waves, Stirring and dispersing evenly and then filtering to obtain a solid; drying the solid and spraying a 1% potassium permanganate solution corresponding to 1% of the weight of the porous carrier particles, and drying to obtain the solid. The porous carrier particles are ceramsite, the particle size is 5±2mm,
[0025] The rare earth chelate is obtained by mixing lanthanum chloride and disodium EDTA with a molar ratio of 1:2.5, and its specific preparation method is:
[0026] Add 1.12g of lanthanum chloride and 3.88g of disodium EDTA into 95g of water, stir and disperse for...
Embodiment 2
[0029] A filler particle comprising diatomaceous earth-based porous ceramics, rare earth chelates, and potassium permanganate.
[0030] Prepared by the following method: 10 parts by weight of diatomite-based porous ceramics (same as Example 1) are distributed in the rare earth chelate solution, and the mass percent concentration of the rare earth chelate in the rare earth chelate solution is 10% Under the action of ultrasonic waves, stir and disperse uniformly and then filter to obtain a solid; after drying the solid, spray a solution of 1% potassium permanganate with a concentration equivalent to 1% by weight of the porous carrier particles, and obtain it after drying.
[0031] The rare earth chelate is obtained by mixing lanthanum chloride and disodium EDTA with a molar ratio of 1:2.5, and its specific preparation method is:
[0032] Add 2.24g of lanthanum chloride and 7.76g of disodium EDTA into 90g of water, stir and disperse for 10-20 minutes.
Embodiment 3
[0034] A filler particle comprising diatomaceous earth-based porous ceramics, rare earth chelates, and potassium permanganate.
[0035] Prepared by the following method: 10 parts by weight of diatomite-based porous ceramics (same as Example 1) are distributed in the rare earth chelate solution, and the mass percent concentration of the rare earth chelate in the rare earth chelate solution is 8% Under the action of ultrasonic waves, stir and disperse uniformly and then filter to obtain a solid; spray the solid with a concentration of 1% potassium permanganate solution equivalent to 0.5% by weight of the porous carrier particles after drying, and obtain it after drying.
[0036] The rare earth chelate is obtained by mixing lanthanum chloride and disodium EDTA with a molar ratio of 1:2.2, and its specific preparation method is:
[0037] Add 2g of lanthanum chloride and 6g of disodium EDTA into 90g of water, stir and disperse for 10-20 minutes.
