Abstract
The invention belongs to a preparation method of impregnated activated carbon, which loads potassium permanganate, malic acid and other substances on wood activated carbon by an impregnation method, so that the activated carbon can adsorb formaldehyde, benzene, organic volatile gas and other properties. The impregnation activityThe packing density of the charcoal is 0.19 to 0.25g/cm3Iodine adsorption > 1000mg/g, specific surface area > 1000m2/g。
Description
One, technical field
The invention belongs to the preparation method of Immesion active carbon, when especially the active charing science of law absorption behind the dipping strengthened, its original physical absorption was constant substantially, and this product has been used for indoor air purification, has obtained good effect.
Two, background technology
Charcoal absorption divides physical absorption and chemisorbed, and physical absorption is the main absorption of active carbon.Physical absorption is: be adsorbed matter and at first contact the active carbon outer surface, the macropore that is communicated with outer surface enters mesopore and enters micropore more then.In micropore and mesopore, attract each other by Van der Waals force gravitation between the molecule of adsorbate and active carbon, adsorbate is adsorbed in the hole.Chemisorbed is: adsorbate with the organo-functional group of activated carbon surface as-OH-,-CH
2-waiting and inorganic CL, the valence electron on H, Ca, Mg, the Fe etc. exchanges or has the power that produces and in conjunction with being adsorbed on the active carbon, chemical reaction takes place promptly.Immesion active carbon belongs to the chemisorbed performance that strengthens or change active carbon.
The preparation of Immesion active carbon at present has the patent disclosure of pair dipping method, condition, as: CN1765489, CN1830542 etc.; At the difference of adsorbate the patent disclosure of various maceration extracts prescriptions is arranged, as: US6514907 etc.But the active carbon of making carrier is not paid attention to, often make active carbon when absorption certain or some physical capacities improve, the original physical absorption power to some materials of active carbon descends, this is because the used carrier active carbon contains mesopore and macropore is few, the material that is written into has enters micropore and mesopore in the active carbon, has made this part hole plug.The present invention is because active carbon mesopore, the macropore of usefulness are more, and packing density is littler than common active carbon, and packing density is 0.19～0.25g/cm
3, common grain charcoal packing density is: 0.35～0.55g/cm
3So the volume of every gram active carbon is just big, so when macerate is written into this active carbon outer surface and part macropore, make the physical absorption of the micropore that plays a major role, mesopore unaffected.The prescription of maceration extract uniqueness all improves absorption affinities such as this charcoal PARA FORMALDEHYDE PRILLS(91,95), benzene, organic volatile gas in addition.This charcoal is better than coconut husk charcoal, bamboo charcoal when being used for indoor air purification.
Three, summary of the invention
The present invention is that to be written into packing density be 0.19～0.25g/cm a kind of method with dipping in ferrous sulfate, potassium bichromate and malic acid, citric acid, the gallic acid
3, active carbon on manufacture method, concrete manufacturing process:
1, indefinite form grain charcoal is made
Description of the process: wood material refers to that wood chip, alditol slag, waste of flax etc. are crushed to certain particle size and wood chip.Activating agent refers to zinc chloride or phosphoric acid.
2, the manufacturing of impregnated carbon
A kind of in ferrous sulfate, potassium bichromate and citric acid, malic acid, the gallic acid added in the water of 500kg, be mixed, pour in the indefinite form grain active carbon of 100kg, room temperature was soaked 2～5 hours, filtered, and oven dry gets final product.
Four, the specific embodiment
Embodiment 1: a kind of 1～5 part of not eating in the acid of 1～10 part of potassium bichromate, 1～8 part in ferrous sulfate, malic acid, citric acid is poured in 500 parts of water, is mixed, and adds 100 parts of wood activated charcoals 1, soaks 2～5 hours, filters, and oven dry gets final product.
Embodiment 2: 1～10 part of potassium bichromate, 1～5 part in ferrous sulfate, malic acid, and in citric acid or the gallic acid a kind of 1～3 part is poured in 500 parts of water, is mixed, and adds 100 parts of wood activated charcoals 2, soaks 2～5 hours, filters, and oven dry gets final product.
Embodiment 3: 1～10 part of potassium bichromate, 1～5 part in ferrous sulfate, malic acid, and in citric acid or the gallic acid a kind of 1～3 part is poured in 500 parts of water, is mixed, and adds 100 parts of coconut husk charcoals, soaks 2～5 hours, filters, and oven dry gets final product.
Reference examples 1: get 500mg water and pour into and soaked in the 100mg carbo lignius 1 2～5 hours, filter, oven dry gets final product.
