Description

Tetroxide tetrsilver coal absorbent charcoal, preparation method and application thereof
Technical field
The present invention relates to a kind of tetroxide tetrsilver coal absorbent charcoal, preparation method and as the application of filtering material.
Background technology
At present, filtering material miscellaneous is a lot of on the domestic market, its purposes is respectively arranged with not enough.And active carbon is exactly one of them, the filter of doing the filtrate manufacturing with active carbon uses certain hour, because active carbon itself has only suction-operated, there is not the sterilization algae removal effect, through charcoal absorption behind the certain hour behind a large amount of organic pollutions, microorganism very easily breeds, organic matter decomposes on the interface of active carbon under action of microorganisms, make organic nitrogen progressively be decomposed into proteinic nitrogen, ammonia nitrogen, nitrite nitrogen, make that content of nitrite increases in the water outlet of active carbon filter, can be in active carbon and filter bed in endophytic bacteria etc. and produce secondary pollution now, so not only do not reach the purpose that purifies water, on the contrary can polluted water.In recent years along with the sterilizing mechanisms of silver is familiar with by people gradually, silver (or carrying silver) active carbon that oozes miscellaneous constantly appears in market, manufacture method mostly is the solution infusion method, there be coming off in various degree in silver, silver is a heavy metal species, be insalubrious, the problem of coming off that how to solve active carbon loading silver silver in water treatment is a difficult problem.
Summary of the invention
Goal of the invention: the object of the invention is to provide a kind of impurity, dirt, nuisance etc. of can adsorbing again can sterilization algae removal, simultaneously silver in water treatment procedure difficult drop-off, can directly apply to the tetroxide tetrsilver coal absorbent charcoal that drinking water filters.
Another object of the present invention is to provide a kind of preparation method of above-mentioned tetroxide tetrsilver coal absorbent charcoal.
Another object of the present invention is to provide the application of this tetroxide tetrsilver coal absorbent charcoal.
Technical scheme: a kind of tetroxide tetrsilver coal absorbent charcoal, it comprises coal mass active carbon and Tetrasilver tetroxide, described Tetrasilver tetroxide adsorbed close is in the aperture of the surface of coal mass active carbon or active carbon.
Tetrasilver tetroxide content in per 100 gram tetroxide tetrsilver coal absorbent charcoals is not less than 0.1 milligram.
Described coal mass active carbon is 9~11 orders.
The preparation method of above-mentioned tetroxide tetrsilver coal absorbent charcoal comprises the steps:
1), that coal mass active carbon cleaning and dry back is standby; Tetrasilver tetroxide and pH value are mixed by weight 0.5~1 ‰ ratio at 7.0~7.5 alkalescent solvent;
2), the mixed liquor in the step 1) is sprayed to temperature on 50~80 ℃ coal mass active carbon;
3) with step 2) in make carry silver-colored coal mass active carbon under 70~90 ℃, promptly obtained tetroxide tetrsilver coal absorbent charcoal in 8~15 minutes at sealing equipment inner drying against sunshine.
Alkalescent solvent described in the above-mentioned steps (1) is a kind of in ammoniacal liquor, sodium hydroxide solution, the aqua calcis.
Above-mentioned coal mass active carbon be 9~11 orders, quality meets the GB/T7702 standard.
Tetroxide tetrsilver coal absorbent charcoal is as the application of filtering material in water purifier and direct drinking water supply project equipment.
Tetroxide tetrsilver coal absorbent charcoal is the honeycomb that utilizes coal mass active carbon abundant, higher intensity, reasonable proportioning, Tetrasilver tetroxide is sprayed to the surface of coal mass active carbon, in certain temperature, under time, the free enthalpy of material increases, the molecule of physical absorption can absorb energy and excite the possibility that enters chemisorbed, in other words, because intermolecular energy excites, surface treated active carbon, its surface free radical group is active, combine closely with silver ion, material increases from the possibility that intermolecular combination carries out the transition to the covalent bonds form, thereby can not come off because of flowing water washes away, a kind ofly can adsorb and kill harmful substance thereby make, the tetroxide tetrsilver coal absorbent charcoal of bacterium.
Beneficial effect: tetroxide tetrsilver coal absorbent charcoal of the present invention can be removed chlorine residue, heavy metal, organic pollution effectively, has solved in the prior art and can only adsorb impurity, bacterium, and it can not have been killed and cause secondary pollution problem.The silver on the tetroxide tetrsilver coal absorbent charcoal surface that preparation method of the present invention makes can not come off, technology simple, can realize large-scale industrial production.Tetroxide tetrsilver coal absorbent charcoal is applied to the purification of water purifier or other direct drinking water projects, particularly in bottled water is produced, need not carry out ozonization in addition and handle and get final product long-period freshness preserving, and the water quality after handling is less scaling, mouthfeel is obviously improved; Water after the processing has kept the natural mineral matter to the human body beneficial; The water quality meta-alkalescence; Dissolved oxygen on average increases about 30%; Have long-acting inhibition bacterium, virus, the effect of algae meets the water standard of the healthy water that domestic and international expert generally acknowledges.
