A kind of Novel sterilizing aqueous solution and preparation technology thereof
Technical field:
The present invention relates to a kind of water and body surface microbiological treatment aqua and preparation technology thereof, be specially a kind of Novel sterilizing aqueous solution and preparation technology thereof.
Background technology:
In life, inevitably contact the microorganisms such as noxious bacteria, fungi and virus, they are the main causes of bringing out mankind's communicate illness.In history, the famous event that infectious disease causes mankind's quantity to decline has, and causes Europe 1/3rd human mortalities' plague mid-term 14th century of Christian era, and 20 beginnings of the century caused the influenza of the whole world more than 2,000 ten thousand people's death.Modern age, the development of science and technology health level did not only make infectious disease wither away, and on the contrary, along with mankind's activity exchanges frequently, the density of population increases, and has caused the disease that traditional microorganism causes to increase.
Harmful microorganism is present among human lives's various water bodies and body surface, and in swimming pool, bathing pool, various tablewares, toilet article, surface of denture, be also present in skin surface, thereby cause very large health problem.
Swimming pool is mainly the sterilization of application chlorine-containing disinfectant at present, but the organic chloride that chlorine-containing disinfectant produces when sterilization, as monochloro methane, carrene, chloroform, tetrachloromethane etc., can work the mischief to health.And another alternative is to add a little Chi at swimming pool discrepancy product, before entering swimming pool or after swimming, therefrom dived with sterilization, but plant disinfection way, process trouble and be difficult to management, wherein add not smelling good of active ingredient smell simultaneously, thereby by people institute need not mostly.
Common plunge bath or public place bathtub are not used by people because microorganism is difficult to process, and cause the large wasting of resources, have changed people's bathing mode.And people still show special preference to for bath in a tub, but at present technology be difficult to make people relieved utilize in public places bathing, be difficult in hotel, hotel used bath in a tub.
The sterilization of various tablewares, toilet article and artificial tooth artificial tooth is also a major issue.Table-ware disinfection at present adopts ultraviolet radiation modality mostly, this can reach certain bactericidal action, but this mode need to be used comparison expensive device, simultaneously as everybody knows a little less than ultraviolet penetration capacity, the effect that the sterilization ,Er lower floor that surface tableware can obtain is difficult to reach.
Now China enters aging society, and old man's number accounts for size of population proportion constantly to be increased, and artificial tooth is installed and is on the increase, and take oral disinfecting problem that artificial tooth, mouthwash be representative, becomes a large field of oral health.The take Chinese herbal medicine, organic compound that on market, occur are at present main thimerosal, but formality is incomplete, and effect is bad.
Therefore at present just need to be a kind of safe and reliable, good stability, bactericide easy to use, can be applied to the daily life fields such as water, tableware, oral hygiene, fabric.Silver is known before 2000 as bactericide, and researcher measures the relative efficiency of different metal antibacterial efficacy according to experiment, arranges as follows:
Ag>Hg>Cu>Cd>Ni>Co>Zn>Fe>Ca
Silver participates in bactericidal activity effect also the different valence state form of expression, and their sterilization relative ability is by as follows to weak arrangement by force: Ag (III) > Ag (II) > Ag (I) > Ag

Summary of the invention:
The object of the present invention is to provide a kind of safe and reliablely, good stability, can be conveniently for water, tableware, and oral hygiene, the Novel sterilizing aqueous solution of the daily lifes such as fabric provides its concrete preparation method simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Novel sterilizing aqueous solution, is specifically comprised of following material and quality proportioning:
Trivalent silver iron compound 0.1-0.3 part,
Ammoniacal liquor 10-30 part,
Water 70-90 part.
Described trivalent silver iron compound can be silver sesquioxide.
The present invention also provides its concrete preparation technology, as follows: first take respectively trivalent silver iron compound 0.1-0.3 part, and ammoniacal liquor 10-30 part, water 70-90 part, then fully stirring and evenly mixing is extremely colourless.
The present invention is easy to use, has very strong bactericidal action, and it can be widely used in the various ambient water sterilizations such as the public places such as hospital, school, swimming pool, bathing pool and family and disinfecting utensils.
Embodiment:
In order better to illustrate, below in conjunction with case study on implementation and experimental result, the present invention is elaborated this patent.
Embodiment 1:
The preparation of sterilization aqua:
Take trivalent silver iron compound 0.1g, measure 20mL ammoniacal liquor, 80mL distilled water, fully stirring and evenly mixing, makes one thousandth trivalent ion silver stoste aqua, i.e. Novel sterilizing aqueous solution.
Test 1:
Get above-mentioned trivalent ion silver stoste aqua 0.1ml and join (bacteria containing amount 100 in 100ml distilled water, 000cpu/mL, test organisms is Escherichia coli), standing 30 seconds, from wherein getting tri-samples of 20 μ l, evenly coat three aseptic flat boards, cultivate 12-14 hour, colony counting, the non-processor bacterium liquid of take is contrast.Result shows that it all can kill trial microorganism 100% in 30 seconds.
Test 2
Get above-mentioned sterilization aqua 100ml and join the 0.5m containing 50 tablewares
3in basin in running water, and put into test organisms staphylococcus aureus, make final bacteria concentration reach 10,000cpu/mL, after 20 minutes, evenly coats three aseptic flat boards from wherein respectively getting at random 20 μ l, cultivate 16-18 hour, colony counting, take do not add sterilization aqua for contrasting.Result shows that it all can kill trial microorganism 100%.Such treatment samples and the control sample that do not add sterilization aqua are placed and to be spent the night simultaneously, peculiar smell not in treatment samples, and the control sample taste that gives out a foul smell.
Above-mentioned trivalent silver iron compound can be prepared by the following method: sodium hydroxide (potassium) 0.1-0.3 part, Tetrasilver tetroxide 1-2 part, sodium peroxydisulfate (potassium) 1-3 part, fully grind and be mixed evenly, grain fineness is 100-200 order, every 10 parts of upper mixtures add 3~5 parts of deionized waters (w/v), furnishing semi-fluid condition, after 50~80 ℃ of insulation 1~2h, filter, and with distilled water flushing at least three times, to wash away unreacted sodium peroxydisulfate (potassium) and sodium hydroxide (potassium) and product sodium sulphate (potassium) impurity, obtain nanometer trivalent silver iron compound.Described trivalent silver iron compound can be silver sesquioxide.
