description | The invention discloses a method for preparing wood activated carbon by a phosphoric acid method. In the method, wood dusts are used as a raw material, phosphoric acid is used as an activating agent, boric acid is used as an activation reaction catalyst, and the wood activated carbon is prepared by a chemical-physical combination method. The preparation method comprises the following steps of: fully mixing and uniformly stirring the wood dusts, the phosphoric acid and the boric acid in the weight ratio of 1: (1.0-3.0): (0.1-0.5) at the temperature of 80 to 150 DEG C, and standing for 3 hours; heating the mixture to the temperature of 300 to 400 DEG C, and performing carbonization and activation for 1 to 4 hours; immersing the obtained material by using hot water and recycling and cleaning the phosphoric acid; and drying the obtained material at the temperature of 120 to 200 DEG C and pulverizing so as to obtain the wood activated carbon. As the boric acid is used as the activation reaction catalyst, the prepa |
