Embodiment 1
[0016] An ultrasonic-assisted hydrothermal synthesis method for preparing metal element-doped activated clay, weighing 4.0 g of activated clay, 2.0 g of barium chloride and 2.0 g of sodium hydroxide, adding 20 ml of distilled water, and stirring with a magnetic stirrer 0.5h, then put it in the ultrasonic cleaner for 2h to make the mixing and dispersion uniform, pour the stirred mixture into the reaction kettle, place it in the oven and set the temperature to 80℃, take it out after 15h reaction, and then put the mixture Carry out suction filtration, washing, and then put it in an oven to dry at 120 ℃ for 7 hours, and finally grind the dried sample into powder to obtain the activated clay doped with metal barium, which is recorded as Ba-MAC, dry 7hours (MAC is modified After the activated clay).
Embodiment 2
[0018] An ultrasonic-assisted hydrothermal synthesis method for preparing metal element-doped activated clay. Weigh 4.0g activated clay, 2.0g barium chloride and 2.0g sodium hydroxide, add 20ml distilled water, and stir with a magnetic stirrer 1.5h, then put it in the ultrasonic cleaner for 2h to make the mixing and dispersion uniform, pour the stirred mixture into the reactor, place it in the oven and set the temperature to 80℃, take it out after reacting for 15h, and then put the mixture Carry out suction filtration, washing, and then put it into an oven to dry at 120°C for 12 hours, and finally grind the dried sample into powder to obtain the activated clay doped with metal barium, which is recorded as Ba-MAC, dry 12 hours.
Embodiment 3
[0020] An ultrasonic-assisted hydrothermal synthesis method for preparing metal element-doped activated clay, weighing 4.0 g of activated clay (Activated clay), 2.0 g of cobalt chloride hexahydrate and 2.0 g of sodium hydroxide, adding 20 ml of distilled water, and magnetically stirring Stir it for 1.5h, then put it in the ultrasonic cleaner for 2h to make the mixing and dispersion uniform. Pour the stirred mixture into the reaction kettle, place it in the oven and set the temperature to 80℃, take it out after reacting for 15h. The mixture was filtered and washed with suction, and then dried in an oven at 120°C for 12 hours. Finally, the dried sample was ground into powder to obtain activated clay doped with metallic cobalt, which was recorded as Co-MAC, dry 12 hours.
