Abstract
A kind of silver-carrying bacteriostatic activated carbon, it is by gac, silver nitrate solution, and potassium bromide solution is formed.There are powerful adsorptive power and silver that the characteristics of bacteriostatic action are arranged according to gac, silver is loaded on the gac, add potassium bromide solution then, silver is securely fixed on the gac, with this gac put into water purifier, mineral pot can reach bacteriostatic action makes the irreproducible purpose of bacterium, do not cause silver to enter in a large number in the water again and cause to exceed standard.The present invention is applicable to that various water purifiers, mineral pot use.
Description
The present invention relates to a kind of silver-carrying bacteriostatic activated carbon, particularly drink water purifying is handled, silver-carrying bacteriostatic activated carbon belongs to the water purification agent field.
As everyone knows, China traditional to drinking water purification.The general alum flocculation agent that adopts, this with the purification style of alum as flocculation agent, can not be enough to reach the heavy metal content that reduces water, water purifier, mineral pot have appearred for this reason, water purifier, mineral pot adopt the method for putting a sterilization bag in water pot to sterilize, this method often exceeds standard to filterable drinking-water bacterium, and its reason is the minority bacterium that enters from environment, in moistening gac due to the series.Be that used gac can not be restrained bacterium and breeds therein, thereby the water that passes through, bacterium often exceeds standard, thereby makes the healthy danger association that is subjected to of drinking person.
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art part provides a kind of sterilization and disinfection, prevents bacterial reproduction, the significant silver-carrying bacteriostatic activated carbon of decontamination effect improving.
The object of the present invention is achieved like this: it is made up of gac, silver nitrate solution, solidifying agent.Their weight proportion is: the per kilogram gac adds the silver nitrate solution of 1 liter of 8-12g/l, the curing agent solution of 1 liter of 6-8g/l.Its best proportioning is the silver nitrate solution of 1 liter of 10g/l of per kilogram gac adding, the potassium bromide solution of 1 liter of 7.5g/l.
Principle effect of the present invention is: have powerful adsorptive power and silver that the characteristics of bacteriostatic action are arranged according to gac.Silver is loaded on the gac, add solidifying agent then, silver is securely fixed on the gac.Can reach bacteriostatic action like this and make the irreproducible purpose of bacterium, not cause silver to enter in a large number in the water again and cause to exceed standard.
Below in conjunction with embodiment in detail the present invention is described in detail:
Gac of the present invention adopts common gac, silver nitrate solution, and solidifying agent adopts potassium bromide solution.Its prescription (weight proportion) and method for making embodiment are as follows:
Embodiment 1, gets 1 kilogram of gac, adds the silver nitrate solution of 1 liter of 8g/l, fully stirs.Mix the back 100 ℃ of dried down baking, add the potassium bromide solution of 1 liter of 6g/l, fully stir evenly, be finished product after the drying to doing.
Embodiment 2. gets 1 kilogram of gac, adds the silver nitrate solution of 1 liter of 10g/l, and abundant the stirring done under 115 ℃ after mixing and baked to dried, adds the potassium bromide solution of 1 liter of 7.5g/l then, fully stirs evenly, and is finished product after the drying.
Embodiment 3. gets 1 kilogram of gac, adds the silver nitrate solution of 1 liter of 12g/l, and abundant the stirring done under 120 ℃ after mixing and baked to dried, adds the potassium bromide solution of 1 liter of 8g/l then, fully stirs evenly, and is finished product after the drying.
Embodiment 4. packs the present invention in the bag, puts in the mineral pot, and the processing water yield of pack amount of the present invention and mineral pot adapts, promptly the water yield of handling high more, the bacteriostatic activated carbon amount of being adorned is also high more.
Embodiment 5. uses the present invention and the assay contrast (table 1) of using common gac bacterium number
Embodiment 6. compares (table 2) by the assay of the different water yields
The assay (table 3) of embodiment 7. different silver carrying amounts and total plate count
| Carry silver (Ag) amount (milliliter/gram) | Total plate count (individual/milliliter) |
| 3 4 5 6.3 7.6 12 | 3×10 33.5×10 30-29 2-35 0-60 0-17 |
The present invention has following advantage compared to existing technology: manufacture craft is simple, purify good antimicrobial effect, (national standard total number of bacteria (100/milliliter) indices all can reach the sanitary standard of national drinking water, thereby is applicable to that various Water purifiers, mineral pot use.
Claims (2)
1, a kind of silver-carrying bacteriostatic activated carbon is characterized in that it is made up of gac, silver nitrate solution, solidifying agent, and its weight proportion is: the per kilogram gac adds the silver nitrate solution of 1 liter-12g/l, the solidifying agent of 1 liter of 6-8g/l.
2, silver-carrying bacteriostatic activated carbon according to claim 1 is characterized in that its optimum weight proportioning is: the per kilogram gac adds the silver nitrate solution of 1 liter of 10g/l, the potassium bromide solution of 1 liter of 7.5g/l.
