Embodiment 1
[0044] Purification of palygorskite: Add 100 parts of palygorskite to 500 parts of water, mechanically stir for 10 minutes, let it stand for 1 minute, take only the upper and middle turbid liquid, centrifuge, dry at 110 ° C, grind into powder, and pass through a 320-mesh sieve ,spare.
[0045] Modification of palygorskite: Add 0.1 part of vinyltrimethoxysilane and 0.1 part of cetyltrimethylammonium chloride to 100 parts of purified palygorskite, stir and mix evenly, then add Water at 60°C, so that the solid-liquid ratio of the system is 1 / 5. After stirring mechanically at room temperature for 5 minutes, add 1.0 parts of activated carbon powder to the mixture system, continue stirring for 5 minutes, and add 0.5 parts of activated carbon powder while stirring. The concentration is 0.1mol / L sodium hydroxide solution, then dried at 110°C, and ground into a powder with a particle size of 100 mesh to 250 mesh.
Embodiment 2
[0047] The purification of palygorskite: same as embodiment 1.
[0048] Modification of palygorskite: Add 0.3 part of γ-aminopropyltriethoxysilane and 0.05 part of cetyltrimethylammonium bromide to 100 parts of net purified palygorskite, stir and mix evenly, and add Add water at 70°C to the mixing system to make the solid-to-liquid ratio of the system 1 / 4. After stirring mechanically at room temperature for 10 minutes, add 2.0 parts of activated carbon powder to the mixture system, continue stirring for 2 minutes, and add 0.3 parts of concentration while stirring. It is 1mol / L sodium hydroxide solution, then dried at 100°C, and ground into a powder with a particle size of 100 mesh to 250 mesh.
Embodiment 3
[0050] The purification of palygorskite: same as embodiment 1.
[0051] Modification of palygorskite: Add 0.5 part of γ-(2,3-epoxypropoxy)propyl trimethoxysilane to 100 parts of net purified palygorskite, 0.01 part of dodecyl trimethyl chloride Ammonium, after stirring and mixing evenly, add water at 80°C to the mixing system to make the solid-to-liquid ratio of the system 1 / 2, mechanically stir at room temperature for 8 minutes, then add 2.0 parts of activated carbon powder to the mixture system, and continue stirring for 8 minutes , Add 0.2 parts of 0.5mol / L sodium hydroxide solution while stirring, then dry at 105°C, and grind it into a powder with a particle size of 100 mesh to 250 mesh.
