Description
Technical field
The present invention relates to a kind of high capacity nano-silver active carbon and preparation method thereof, specifically, is the preparation method that a kind of technique is simple, cost is low, security is high, is applicable to industrial production; Different size carrying nano silver active carbon can be prepared with satisfied different demand, can be used for preparation sewage disposal, exhaust-gas treatment, antibacterially to keep a public place clean, environmental protection and the Related product such as purification, chemical catalysis, have a extensive future.
Background technology
Reform and opening-up three during the last ten years, China's economy and society achieve continuously and healthily with deep development.In this process, along with industrial manufacturing industry and agriculture fast development, environmental problem is on the rise.Wherein, water quality deterioration and atmosphere pollution serious threat is to the health of people and productive life.How effectively administering water and atmosphere pollution, the water that the protection mankind depend on for existence and Air resource, realize the sustainable development of economic society, just becomes more and more urgent and important.
In many water and atmospheric treatment technology, active carbon adsorption technology is a kind of getting instant result and cheap method.But also there is its drawback in active carbon adsorption technology, such as, hydrophobic due to activated carbon surface, add huge specific area, effectively to remove in water body while organic compound and part inorganic impurity, also for the breeding of the microorganisms such as bacterium provides hotbed, make active carbon itself also become pollution sources, cause the secondary pollution of water body and affect purifying water effect.In order to overcome this defect, we consider to carry out carrying silver process to active carbon, become carrying nano silver active carbon after activated carbon-carried nano silver.Carrying nano silver active carbon not only can keep the function of organic compound in adsorbed water and part inorganic matter, and its Nano Silver carried also can effectively anti-bacteria, the mould even microbial growth of virus be bred.Research finds, carrying nano silver active carbon is compared with normal activated carbon, and the speed of not only decontamination removal of impurities is accelerated, and efficiency also gets a promotion greatly, and effectively can suppress microbial reproduction, prevents active carbon from becoming secondary pollution source.
In the active carbon of all multiple types, we have selected that specific area is large, hole is flourishing and the active carbon of good mechanical property is carrier, and the moisture wherein contained by shell activated carbon and ash content are all lower, thus preferably shell activated carbon as Nano Silver carrier.On the other hand, research shows, the bactericidal ability of carrying nano silver active carbon is relevant with Nano Silver particle diameter to silver carrying amount.The silver carrying amount of active carbon is higher, and Nano Silver particle diameter is less, and bactericidal and bacteriostatic effect is better.Therefore the present invention increases activated carbon surface by the method activated active carbon and silver carrying amount is improved in intrapore year silver-colored site.Meanwhile, we are pre-synthesis is no more than the nano-Ag particles of 200nm, it can be used as Nano Silver medium.
The disclosed method of Chinese patent " active carbon of loading nano silvery and preparation method thereof " (publication number: CN103232035A) is, rice hull active carbon is added in deionized water, adjust ph is 9 ~ 11, add valence state silver compound and a complexing agent again, add chemical reducing agent after being uniformly mixed, fully after reaction, namely obtain the active carbon of loading nano silvery.The method is after the complex compound of charcoal absorption one valence state silver, use reducing agent again, the complex compound of the valence state silver that active carbon adsorbs is reduced, obtain carrying nano silver active carbon, but the nano-Ag particles on carrying nano silver active carbon is reunited serious, distribution of particles is uneven, and Nano Silver is mainly distributed in activated carbon surface, the distribution of internal void Nano Silver is less, and finally cause silver carrying amount low, the sterilization anti-microbial property of carrying nano silver active carbon is had a greatly reduced quality.On the other hand, although last handling process still have passed through take out steps such as washing oven dry, but due to the superpower adsorptivity of active carbon, cause the impurity compound of active carbon inside absorption and ion etc. residual serious, this can affect water treatment efficiency, and the complex compound that these impurity compounds and ion are all reduction one valence state silver is brought into.
Chinese patent " preparation method of antibacterial fibre of activated carbon containing nano silver particles " (publication number: CN1376822) disclosed method method disclosed with " active carbon of loading nano silvery and preparation method thereof " (publication number: CN103232035A) in principle is the same, difference is, the complex compound of what NACF directly adsorbed is not a valence state silver, but directly adsorb a valence state silver, then the reproducibility of NACF is utilized, one valence state silver of absorption is at high temperature reduced, becomes carrying nano silver active carbon.Although do not add other reducing agents and complexometric reagent, but the NACF that phosphoric acid dip is crossed is to the limited sorption capacity of a valence state silver, silver carrying amount can be affected, and Nano Silver domain size distribution after reduction uneven with, mainly also be distributed in activated carbon surface, be difficult to be formed and stablize lasting absorption and antibacterial bacteriostatic effect.
