method and uses thereof
Inventor(s): KAIMING JIANG, etal.
The invention has discloses a tetrasilver tetroxide coal activated
carbon, a preparation method and an application; the tetrasilver
tetroxide coal activated carbon contains coal activated carbon and
tetrasilver tetroxide; the tetrasilver tetroxide is adsorbed on
the surface or the aperture of the coal activated carbon. The
preparation method is as follows: the coal activated carbon is
washed and dried for stand-by; the tetrasilver tetroxide is
blended with an alkalescent solvent; the blended liquid is sprayed
on the coal activated carbon; a silver-loaded coal activated
carbon is re-dried so as to obtain the tetrasilver tetroxide coal
activated carbon. As a filter material, the tetrasilver tetroxide
coal activated carbon is applied in a water cleaner and a direct
drinking water supply project. The silver on the surface of the
tetrasilver tetroxide coal activated carbon prepared by the
preparation method cannot fall off; the tetrasilver tetroxide coal
activated carbon can be applied to the water cleaner and other
direct drinking water projects to effectively adsorb and kill
bacteria and a hazardous substance and produce drinking water
which is clean and useful for human health and meets a hygienic
standard of people.
The present invention relates to a tetroxide four silver activated
carbon from coal preparation methods and applications as a filter
At present, the domestic market a wide range of filter material
many different purposes and disadvantages.
The activated carbon is one of them, using activated carbon as the
filter media manufactured to a certain time, because the activated
carbon adsorption of itself only, no sterilization effect, after a
certain period of time a large number of activated carbon
adsorption of organic contaminants, the microbial pole easy to
breed, decomposition of organic matter under the action of
microorganisms on activated carbon interface, allowing the gradual
decomposition of organic nitrogen-protein nitrogen, ammonia
nitrogen, nitrite nitrogen, making the activated carbon filter to
increase the nitrite content of the water will be in the activated
carbon within and filter bed hereby raw bacteria to produce
secondary pollution, it will not only reach the purpose of water
purification, it will pollute the water.
In recent years, with the sterilization principle of silver
gradually recognized, emerging markets a wide range of
permeability silver (or silver) activated carbon, the
manufacturing method for the solution of most of the immersion
method, there are different degrees of loss of silver, silver is a
heavy metal , it is harmful to the body, how to solve the problem
of silver activated carbon in the fall of silver water is a
SUMMARY OF THE INVENTION
OBJECTS OF THE INVENTION:
The purpose of the present invention to provide a both adsorption
of impurities, dirt, and other harmful substances can
sterilization, silver in the treatment process at the same time
easy to fall off, and can be applied directly to the drinking
water filtration tetroxide four silver activated carbon from coal.
Another object of the present invention to provide a method for
preparing the above tetroxide four silver activated carbon from
Another object of the present invention is to provide the
tetroxide four silver activated carbon from coal applications.
Technical Solution: A tetroxide four silver activated carbon from
coal, which includes coal activated carbon and tetroxide four
silver, the tetroxide four silver tightly adsorbed on the inner
surface of the activated carbon from coal or charcoal aperture.
Per 100 g tetroxide four silver activated carbon from coal in
tetroxide four silver content of not less than 0.1 mg.
The Coal activated carbon 9 to 11 mesh.
It said tetroxide four silver activated carbon from coal
preparation method comprises the following steps:
1), the activated carbon from coal after washing and drying stand;
tetroxide four silver and a weight ratio of PH value 0.5 ~ 1 ‰
proportions in a weak alkaline solvent 7.0 to 7.5;
2) the step 1) spraying the mixture to a temperature at 50 ~ 80 ?
activated carbon from coal on;
3) Step 2) obtained silver activated carbon from coal at 70 ~ 90
?, drying in the light of the anti-seal equipment 8 to 15 minutes
to obtain tetroxide four silver activated carbon from coal.
The above step (1) of the weakly basic solvent is ammonia, sodium
hydroxide solution, calcium hydroxide solution in one.
The above-described activated carbon from coal is 9 to 11 mesh,
the quality of GB / T7702 standards.
Tetroxide four silver coal activated carbon as a filter material
in water purifier and drinking water supply project equipment.
Tetroxide four silver activated carbon from coal is the use of
activated carbon from coal-rich cellular structure, high strength,
reasonable ratio, the four-four silver oxide coating to the
surface of activated carbon from coal, at a certain temperature,
time, matter free enthalpy increases, the molecule can absorb
energy of physical adsorption and chemisorption excitation
probability of entry, in other words, since the excitation energy
between molecules, the surface-treated activated carbon, active
surface free radicals, combined with silver ions close, substance
the possibility of combining the Intermolecular transition to form
covalent bonds increases, and thus will not fall off due to water
erosion, thereby obtaining a can absorb and kill the harmful
substances, bacteria tetroxide four silver activated carbon from
Beneficial effects: tetroxide four silver coal activated carbon of
the present invention can effectively remove chlorine, heavy
metals, organic pollutants, can only be solved in the prior art
adsorption of impurities, bacteria, and not be able to kill and
cause secondary pollution The problem.
The preparation process of the present invention obtained
tetroxide four silver activated carbon from coal will not fall off
the surface of the silver process is simple, can achieve
large-scale industrial production.
The tetroxide four silver activated carbon from coal applied to
purify water or other drinking water projects, especially in
bottled water production, without additional ozone disinfection
process can be long-term preservation, and the treated water is
not easy to scale, taste significantly improved; the treated water
retains natural minerals beneficial to human body; water quality
alkaline; dissolved oxygen increased by an average of about 30%;
with long-lasting inhibition of bacteria, viruses, algae effect,
in line with domestic and foreign experts recognized health water
