Stirring at normal temperature 6-10h, filtering, solid product after drying, mix under the conditions of temperature is less than 80 DEG C with manganese sulfate solution, stir 5-
10h, filtering, is washed with distilled water 3-5 times, after being dried at 100 DEG C or less, roasts live to get modified under inert gas protection
Property charcoal.
Preferably, the calcination temperature is 580-640 DEG C, roasting time 4-15h.
Preferably, the inert gas is at least one of nitrogen, argon gas, helium.
Preferably, a concentration of 0.65-0.95mol/L of the potassium permanganate solution.
Preferably, a concentration of 0.5-1.5mol/L of the manganese sulfate.
Preferably, the invention also provides the preparation method of above-mentioned adsorbent, include the following steps：
S1, the two is added totally after by weight mixing 15-30 parts of polyethylene polyamine polymer and 1-4 parts of polyethylene glycol
The deionized water dilution of 1-5 times of product, obtains solution a；
S2, by weight by 60-80 parts of modified activated carbon, 15-30 parts of sepiolite, 10-20 parts of zeolite, microcrystalline cellulose 5-
10 parts, 10-20 parts of diatomite, 0.5-2 parts of nano-titanium dioxide, 0.5-2 parts of Nano zinc dioxide impact-resistant be added in solution a, then control
Temperature processed is 50-95 DEG C, after keeping the temperature 10-30h；Vacuum drying is to get high-performance formaldehyde absorbing under the conditions of temperature is less than 75 DEG C
Agent.
The present invention, then will absorption using modified activated carbon, sepiolite, zeolite, microcrystalline cellulose, diatomite as absorption carrier
Carrier is reacted with the mixed liquor of polyethylene polyamine polymer and polyethylene glycol, in a large amount of amidine functional groups of absorption carrier Surface Creation
With a small amount of hydroxy functional group, amidine functional group can rapidly be reacted with formaldehyde gas, and hydroxyl can enhance the moisture absorption of adsorbent surface
Performance forms water membrane in adsorbent surface, to promote formaldehyde in adsorbent surface absorption, be enriched with, quickening reaction speed,
Improve purifying formaldehyde efficiency；And there is activated carbon a large amount of microcellular structure and larger specific surface area, PARA FORMALDEHYDE PRILLS(91,95) to have extremely strong
Absorption property, using activated carbon as absorption carrier and with the same sepiolite with abundant porous structure, zeolite, microcrystalline cellulose,
Diatomite is used cooperatively, and goes effect of formaldehyde good；Catalyst nano titanium dioxide, Nano zinc dioxide impact-resistant are also carried on suction by the present invention
Attached carrier surface, nano-titanium dioxide, Nano zinc dioxide impact-resistant cooperation illumination use, can capture the electronics in formaldehyde, make formaldehyde point
Sub- active oxidation is degraded to the inorganic substances such as carbon dioxide and water, to realize the photocatalysis Decomposition of PARA FORMALDEHYDE PRILLS(91,95)；The present invention is also right
Primary attachment carrier active carbon is modified, and by the modified of potassium permanganate and manganese sulfate, activated carbon surface is formed largely
Microcellular structure further increases the physical adsorption property of PARA FORMALDEHYDE PRILLS(91,95), and modified activated carbon surface can generate and largely contain
Oxygen functional group, these oxygen-containing functional groups can be reacted with formaldehyde, further enhance the chemisorption performance of PARA FORMALDEHYDE PRILLS(91,95)；Pass through modification
Processing is also so that activated carbon surface generates a large amount of Mn oxide, and Mn oxide PARA FORMALDEHYDE PRILLS(91,95) has higher reactivity, makes to bear
The activated carbon PARA FORMALDEHYDE PRILLS(91,95) for carrying Mn oxide has higher absorption property.To sum up, the present invention passes through to physical absorption, chemistry
Absorption and photocatalysis Decomposition technology are used cooperatively, except formaldehyde is had excellent performance, the high-performance formaldehyde absorbing for preparing of the present invention after tested
Degradation Formaldehyde rate of the agent in 24 hours reaches 99% or more.
