| description | A preparation and application method of a fluoride-removal compound adsorption material by using garlic straw waste belongs to the field of water purification materials. The preparation and application method comprises the following steps: collecting garlic straw waste, washing and drying, smashing, and screening to obtain particles; adding the particles into water or an alkaline solution, repeatedly immersing and changing water, and draining; immersing the particles in food-grade inorganic acid or small molecular weight organic acid, repeatedly operating for five rounds, and dividing the processed particle material into two parts, drying one part instead of the other part, immersing the undried particle material in water containing high-valent metal ions, repeatedly operating for five rounds, draining and drying; uniformly mixing and screening the two different particle materials according to the mass ratio of 1: 1-10 to obtain particles having the average particle size of 2 mm, namely the compound adsorptio |
