More Information
Summary:The invention discloses hemp-stem active carbon, of which the specific surface area is 800-3,000m /g, the total pore volume is 0.5-1cm /g and the pore diameter is 0.5-4nm. The hemp-stem active carbon has a layered micropore-mesopore structure. The invention further discloses a preparation method of the hemp-stem active carbon, a forming method of hemp-stem active carbon and application of formed hemp-stem active carbon in preparation of a filter element of a water purifier. The hemp-stem active carbon provided by the invention has a layered micropore-mesopore structure, a super-large specific surface area and a high pore volume and can absorb various impurities in water more easily.
