Abstract
The invention discloses a process for preparing silver-loaded activated carbon, which comprises the following steps of: firstly, blowing refined nutshell carbon out of dust; secondly, screening particulate nutshell carbon with the particle size of 20 to 30 meshes; thirdly, drying the screened particulate nutshell carbon at 50 to 80 DEG C; fourthly, placing the dried particulate nutshell carbon into a high-temperature revolving furnace and performing regulation for 2 to 4 hours; fifthly, adding aqueous silver obtained by treatment at 900 DEG C into the revolving furnace with carbon powder, and performing heating revolution for 3 to 5 hours to exchange silver ions into micropores of the carbon powder for fixation and shaping and make silver content is 0.001 to 0.6 percent based on the dry weight of the silver-loaded activated carbon; and finally, naturally cooling the fixed and shaped silver-loaded activated carbon and transferring the cooled silver-loaded activated carbon into a vacuum-tight container for later use. The silver-loaded activated carbon prepared by the method has the composite effects of the photochemically-catalytic antibacterial action of titanium dioxide, organic matter decomposition function and the sterilization function of silver ions.
Description
Technical field
The present invention relates to a kind of manufacture craft of anti-biotic material, especially relate to the manufacture craft of a kind of year silver-colored activated carbon.
Background technology
Active carbon is a kind of very good adsorbent, and it has the double grading of physical absorption and chemisorbed, is widely used in the various aspects of industry, agricultural production.Particularly use very extensive with the water purification field that we live relevant.The anti-microbial property of silver has been applied to a lot of fields, as bactericide, antiseptic dressing, purifier etc.Silver and the combining of pathogenic bacteria metabolic enzyme lose activity enzyme, make germ not energy metabolism and death; The peptide glycan reaction that exposes on silver and the bacteria cell wall forms the invertibity compound, makes it not advance cell to oxygen transport, prevents the germ activity, causes its death.
DNA base combination in silver and the pathogenic bacteria, silver ion forms cross-linked each other, causes the dna structure sex change, suppresses it and duplicates, and germ is lost activity; Oxygen effect in silver and the water and air can produce reactive oxygen species, and these materials can destroy intracellular various important biomolecule macromolecule and film, also can form other activating oxide, destroys growth and the breeding of bacterium.Silver and combining of carbon are made a year silver-colored activated carbon and have been widely used on the purifier etc., yet, the manufacture craft of existing year silver-colored activated carbon is unreasonable, silver particles aggregates into big particle cluster usually, and big particle cluster is difficult for being adsorbed on the activated carbon, in case meet water then come off easily and run off, thereby influence sterilizing ability.
Summary of the invention
The present invention be directed to defective that the above-mentioned background technology exists a kind of manufacture craft of carrying silver-colored activated carbon of composite effect of photocatalysis antibacterial, decomposing organic matter function and the silver ion for sterilization with titanium dioxide is provided.
For achieving the above object, the invention discloses the manufacture craft of a kind of year silver-colored activated carbon, it comprises the steps: at first, will make with extra care fruit shell carbon and blow out dust through hair-dryer, and secondly, crossing and filtering out granularity is 20～30 purpose particle fruit shell carbons; The 3rd, the particle fruit shell carbon that filters out is carried out drying by 50 ℃～80 ℃ temperature to be handled, the 4th, the particle fruit shell carbon after drying handled is put into the high temperature revolving burner, and described revolving burner when rotated and last 2～4 hours by 250 ℃～280 ℃ temperature the aperture of carbon granule is adjusted; The 5th, will and become watery silver material to add in the described converter that carbon granule is housed through 900 ℃ of high temperature, carry out 3～5 hours the rotation of heating, Ag ion exchange is advanced fixing shaping in the micropore of carbon granule and make the content of silver is to carry 0.001～0.6% of silver-colored activated carbon dry weight; At last, change in the vacuum seal vessel after described year silver-colored activated carbon after fixing the shaping cooled off naturally stand-by.
Further, described silver material is silver peroxide.
Further, described silver material is silver nitrate.
Further, described activated carbon is pure active carbon.
Further, described activated carbon is a cocoanut active charcoal.
Further, described activated carbon is attached to the active carbon on other carrier.
Further, described carrier is woven cloth, nonwoven or felt and fiber.
In sum, the present invention is carried the manufacture craft of silver-colored activated carbon by described silver material is arranged on than the rational proportion scope with described shell, and the aperture of carbon granule is adjusted by 250 ℃～280 ℃ more suitable high temperature, after will and becoming watery silver material to exchange in the micropore of carbon granule into through 900 ℃ of high temperature, thereby can make the covalent bonds of silver and charcoal, final realization has the composite effect of photocatalysis antibacterial, decomposing organic matter function and the silver ion for sterilization of titanium dioxide.
The specific embodiment
For further understanding feature of the present invention, technological means and the specific purposes that reached, function, the present invention is described in further detail below in conjunction with the accompanying drawing and the specific embodiment.
The manufacture craft that silver-colored activated carbon is carried in the present invention comprises the steps: at first, to make with extra care fruit shell carbon and blow out dust through hair-dryer, draw clean particle fruit shell carbon, thereby the abundant outer surface with described particle fruit shell carbon in the carbon hole that makes the particle fruit shell carbon links, and realizes the maximization of particle fruit shell carbon surface area.Next, crossing and filtering out granularity is 20～30 purpose particle fruit shell carbons; The 3rd, the particle fruit shell carbon that filters out is carried out drying by 50 ℃～80 ℃ temperature handle.
The 4th, particle fruit shell carbon after the drying processing is put into the high temperature revolving burner, described revolving burner when rotated and last 2～4 hours by 250 ℃～280 ℃ temperature the aperture of carbon granule is adjusted, make it to be suitable for being written into silver ion, and when implanting silver ion, can mix the internal diameter difficult drop-off of charcoal fully.The 5th, will and become watery silver material to add in the described converter that carbon granule is housed through 900 ℃ of high temperature, carry out 3～5 hours the rotation of heating, Ag ion exchange is advanced fixing shaping in the micropore of carbon granule and make the content of silver is to carry 0.001～0.6% of silver-colored activated carbon dry weight.At last, change in the vacuum seal vessel after described year silver-colored activated carbon after fixing the shaping cooled off naturally stand-by.
Described silver material can be silver peroxide or silver nitrate, and described activated carbon is a pure active carbon or attached to the active carbon on other carrier, described carrier can be woven cloth, nonwoven or felt and fiber etc.In the present embodiment, described silver material is silver nitrate, and described activated carbon is a cocoanut active charcoal.
