Embodiment 1
[0038] One, the preparation method of the tertiary amine oxide modified attapulgite containing rosin base ternary phenanthrene ring structure comprises the following steps:
[0039] (1) Acid-treated attapulgite
[0040]Grind the attapulgite fully, pass through a 200-mesh sieve, and then add the sieved attapulgite powder to 2mol / L hydrochloric acid solution, the mass volume ratio of the added attapulgite powder to hydrochloric acid is 1:10, and the reaction Ultrasonic dispersion was carried out at 60°C for 15 minutes, and the ultrasonic power was 50 W. After the reaction was completed, the precipitate was collected by filtration, and the precipitate was washed until neutral to obtain acidified attapulgite.
[0041] (2) Firing: Add water to the attapulgite obtained in step (1) to prepare a thick liquid, centrifuge at a speed of 5000 rpm to remove the supernatant, and then fire it in a tube furnace in a nitrogen environment at 400 ° C. Adjust the heating rate to 50 ℃ / min, the fi...

[0048] One, the preparation method of the tertiary amine oxide modified attapulgite containing rosin base ternary phenanthrene ring structure comprises the following steps:
[0049] (1) Acid-treated attapulgite
[0050] Grind the attapulgite fully, pass through a 100-mesh sieve, then add the sieved attapulgite powder into 1mol / L nitric acid solution, the mass volume ratio of the added attapulgite powder to nitric acid is 1:20, and the reaction Ultrasonic reaction was carried out at 80°C for 30 minutes, and the ultrasonic power was 30W. After the reaction was completed, the precipitate was collected by filtration, and the precipitate was washed until neutral to obtain acidified attapulgite.
[0051] (2) Firing: centrifuge the attapulgite soil thick liquid obtained in step (1) at a speed of 5000 rpm to remove the supernatant, and then fire it in a tube furnace in a nitrogen environment at 300°C, and adjust the heating rate to 50°C / min , the firing time is set to 1h, and then it...
Embodiment 3
[0057] One. The preparation method of the tertiary amine oxide modified attapulgite containing the rosin-based ternary phenanthrene ring structure comprises the following steps:
[0058] (1) Acid-treated attapulgite:
[0059] Grind attapulgite fully, pass through a 200-mesh sieve, and then add the sieved attapulgite powder into 4mol / L sulfuric acid solution, and the mass volume ratio of the added attapulgite powder to hydrochloric acid is 1:15 , ultrasonic reaction at a reaction temperature of 70° C. for 20 minutes, and an ultrasonic power of 60 W. After the reaction was completed, the precipitate was collected by filtration, and the precipitate was washed until neutral to obtain acidified attapulgite.
[0060] (2) Firing: Centrifuge the attapulgite soil thick liquid obtained in step (1) at a speed of 5000 rpm to remove the supernatant, and then fire it in a tube furnace in a nitrogen environment at 350°C, and adjust the heating rate to 50°C / min , the firing time is set to 1h...
