Abstract

The invention relates to Fe<3+> antibiotic fungi residue activated carbon as well as a preparation method and application thereof. The preparation method comprises the following steps: drying and grinding antibiotic fungi residues; dipping the ground fungi residues in a Fe<3+> salt solution, oscillating and filtering; drying the filtered fungi residues; baking the dried fungi residues, cooling, washing and drying to obtain the activated carbon. The preparation method is simple to operate, and can realize harmless utilization of the antibiotic fungi residues; in addition, the preparation methodcan be used for increasing the loading capacity of Fe<3+>, and also can increase the internal micropore amount of the activated carbon; the Fe<3+> antibiotic fungi residue activated carbon prepared by the method has the characteristics of being large in specific surface area, dense in internal micropores and high in porosity and content of the loaded Fe<3+>.

Description

technical field [0001] The invention relates to the field of environmental materials and air pollution, in particular, to a loaded Fe 3+ Antibiotic bacteria residue activated carbon and its preparation method and application. Background technique [0002] At present, there are many kinds of substrates used for firing activated carbon, such as various livestock and poultry manure, straw, rice husk, bamboo, leaves and sludge; various functional modified activated carbons are used to absorb water, soil and substrates. Various heavy metals, oxygen-containing functional groups, organic matter and gas pollutants in mud; such as Cd, Pb, Cu, Zn and other heavy metals, especially the best adsorption effect on Pb; and carboxyl, hydroxyl, pesticides, herbicides, etc. Oxygen functional groups and organic matter; as another example, various odors, sulfur oxides, nitrogen oxides and other gases, especially for sulfur-containing inorganic substances, have the best adsorption effect.
