Examples
Embodiment 1
[0026] Example 1: The activated carbon with 200 holes / square inch was cut into a cylinder with a diameter of 16 mm and a height of 50 mm, and dried in an oven at 120° C. for 1 hour. Prepare 2.5ml of 5% copper nitrate solution. Take M n+ : CO(NH 2 ) 2 Weigh urea at a ratio of 1:2, and fully dissolve the urea in the copper nitrate solution.
[0027] The solution was dropped on the activated carbon and immersed for 1 hour, and then dried in an oven at 100°C for 1 hour.
[0028] The dried activated carbon is calcined at 300° C. for 2 hours under vacuum and nitrogen protection to obtain modified activated carbon.
Embodiment 2
[0029] Example 2: The activated carbon with 200 holes per square inch was cut into a cylinder with a diameter of 16 mm and a height of 50 mm, and dried in an oven at 120° C. for 1 hour. Prepare 2.5ml of 20% copper nitrate solution. Take M n+ : CO(NH 2 ) 2 Weigh urea at a ratio of 1:4, and fully dissolve the urea in the copper nitrate solution.
[0030] The solution was dropped on the activated carbon and immersed for 1 hour, and then dried in an oven at 100°C for 1 hour.
[0031] The dried activated carbon is calcined at 250° C. for 2 hours under vacuum and nitrogen protection to obtain modified activated carbon.
Embodiment 3
[0032] Example 3: The activated carbon with 200 holes / square inch was cut into a cylinder with a diameter of 16 mm and a height of 50 mm, and dried in an oven at 120° C. for 1 hour. Prepare 2.5 ml of a mixed solution of 10% copper nitrate and 10% cerium nitrate. Take M n+ : CO(NH 2 ) 2 Weigh urea at a ratio of 1:2, and fully dissolve the urea in the copper nitrate solution.
[0033] The solution was dropped on the activated carbon and immersed for 1 hour, and then dried in an oven at 100°C for 1 hour.
[0034] The dried activated carbon is calcined at 250° C. for 2 hours under vacuum and nitrogen protection to obtain modified activated carbon.
