Embodiment 1
[0017] Example 1 Weigh 1KG carrier activated carbon, remove impurities and dust with clean water, weigh copper nitrate 20G, iron nitrate 150G, nickel nitrate 80G, manganese nitrate 30G, potassium nitrate 20G, titanium tetrachloride 1ML, sodium metavanadate 5G, Cobalt nitrate 15G is mixed and dissolved, and then the cleaned activated carbon is immersed in the prepared solution for 48 hours, so that the metal salt is fully absorbed by the activated carbon. The immersion time is 36-48 hours. After immersion, it is dried in the sun, and then put in after drying. High-temperature curing in the oven, the high-temperature curing temperature is 280-320 degrees, and the high-temperature curing time is 12-15 hours. After the curing is completed, it is cooled naturally, and then the finished product is sieved and packaged into storage.
Embodiment 2
[0018] Example 2 Weigh 1KG carrier activated carbon, remove impurities and dust with clean water, weigh copper nitrate 20G, ferric nitrate 120G, nickel nitrate 100G, manganese nitrate 40G, potassium nitrate 20G, titanium tetrachloride 1ML, sodium metavanadate 5G, Cobalt nitrate 15G is mixed and dissolved, and then the cleaned activated carbon is immersed in the prepared solution for 48 hours, so that the metal salt is fully absorbed by the activated carbon. The immersion time is 36 hours. After immersion, it is dried in the sun, and then placed in the oven High-temperature curing, the temperature of high-temperature curing is 280 degrees, and the time of high-temperature curing is 12 hours. After curing is completed, it is cooled naturally, and then the finished product is sieved and packaged into storage.
Embodiment 3
[0019] Example 3 Weigh 1KG carrier activated carbon, remove impurities and dust with clean water, weigh copper nitrate 20G, iron nitrate 150G, nickel nitrate 90G, manganese nitrate 25G, potassium nitrate 15G, titanium tetrachloride 1ML, sodium metavanadate 5G, Cobalt nitrate 15G is mixed and dissolved, and then the cleaned activated carbon is immersed in the prepared solution for 48 hours, so that the metal salt is fully absorbed by the activated carbon. The immersion time is 36-48 hours. After immersion, it is dried in the sun, and then put in after drying. High-temperature curing in the oven, the high-temperature curing temperature is 280-320 degrees, and the high-temperature curing time is 12-15 hours. After the curing is completed, it is cooled naturally, and then the finished product is sieved and packaged into storage.
