Abstract
The invention discloses a kind of inorganic bromine disinfectant, constituted including following raw material according to parts by weight：Effective 1 30 parts of bromine bromine source, 1 25 parts of effective bromine carrier, 0.5 10 parts of effective bromine passivator, 40 97.5 parts of water.The disinfectant of inorganic bromine class of the invention is more better than chlorinated product, green safety in environmental protection；Efficiency of the disinfectant of inorganic bromine class on blue algae killing is more preferable than chlorinated product；The disinfectant of inorganic bromine class of the invention is better than traditional algicide more in the destruction of aqueous systems.
Description
Technical field
The present invention relates to the field of sterilizing, and in particular to a kind of inorganic bromine disinfectant and its preparation method and application.
Background technology
With the growth at aqueous systems age, the eutrophication of aqueous systems will turn into increasingly severe problem.China is very
Many aqueous systems all suffer from such challenge now, Taihu Lake, Poyang Lake and have the Dian Chi of blue-green algae problem throughout the year all
Be faced with such problem, how algae to be carried out in the case where aqueous systems are not influenceed effective control become it is more and more
The problem of scientist's research.What the existing blue-green algae in life drinking water source of China carried out killing is sodium hypochlorite, but
Influence of the chlorinated product to environment and health is increasingly valued by the people.
The content of the invention
Goal of the invention：First technical problem to be solved of invention there is provided a kind of inorganic bromine disinfectant.Invention
Second technical problem to be solved there is provided the preparation method of above-mentioned inorganic bromine disinfectant.It is to be solved by this invention
3rd technical problem there is provided the application of above-mentioned inorganic bromine disinfectant.Can be used to aqueous systems blue-green algae the present invention relates to one kind kill
The inorganic bromine class disinfectant for going out, substitutes inorganic chlorinated product and blue-green algae is killed using the disinfectant of inorganic bromine class.Demonstrate,proved through experiment
Bright, inorganic bromine class disinfectant involved in the present invention is better than inorganic chlorinated product 20%, and green ring to the killing effect of algae
Protect.
Technical scheme：To achieve the above object, the present invention is achieved through the following technical solutions：A kind of inorganic bromine disinfectant,
Constituted including following raw material according to parts by weight：Effective source 1-30 parts of bromine bromine, 1-25 parts of effective bromine carrier, effective bromine passivator
0.5-10 parts, water 40-97.5 parts.
Wherein, above-mentioned effective bromine bromine source is simple substance bromine, liquid chlorine, sodium bromide, KBr, calcium bromide, the one kind in magnesium bromide
Or several compositions.
Wherein, the carrier of above-mentioned effective bromine is urea and NaOH.
Wherein, above-mentioned effective bromine passivator refers to by sodium phosphate, sodium dihydrogen phosphate, one or more groups in disodium hydrogen phosphate
Into.
The preparation method of above-mentioned inorganic bromine disinfectant, comprises the following steps：First effective bromine carrier is dissolved in water, so
Effective bromine bromine source is added when 0-100 DEG C afterwards, then stirring and dissolving adds effective bromine passivator, fully dissolving in room temperature
Afterwards, stir 30 minutes.
Application of the above-mentioned inorganic bromine disinfectant in terms of killing prepares blue algae killing disinfectant.
Beneficial effect：Compared with prior art, advantages of the present invention is as follows：The disinfectant of inorganic bromine class of the invention is in ring
More it is better than chlorinated product, green safety on guarantor；Efficiency of the disinfectant of inorganic bromine class on blue algae killing is more preferable than chlorinated product；This
The disinfectant of the inorganic bromine class of invention is better than traditional algicide more in the destruction of aqueous systems.
Specific embodiment
Following non-limiting examples can make one of ordinary skill in the art be more fully understood the present invention, but not with
Any mode limits the present invention.

After sodium dihydrogen, fully dissolving, stir 30 minutes.
Embodiment 4
First 12g urea and 8g NaOH are dissolved in 45g water, then 30g simple substance is slowly added to when 100 DEG C
Then bromine, stirring and dissolving adds 5g sodium phosphates and 5g sodium dihydrogen phosphates in room temperature, fully after dissolving, stirs 30 minutes.
Embodiment 5
First 5g urea and 5g NaOH are dissolved in 45g water, then 30g brominations is slowly added to when 100 DEG C
Then calcium, stirring and dissolving adds 5g sodium dihydrogen phosphates in room temperature, fully after dissolving, stirs 30 minutes.
Embodiment 6
First 5g urea and 5g NaOH are dissolved in 45g water, then 30g brominations is slowly added to when 100 DEG C
Then magnesium, stirring and dissolving adds 5g disodium hydrogen phosphates in room temperature, fully after dissolving, stirs 30 minutes.
Experimental example 1
It is 1ppm's that thimerosal in embodiment 1-6 is respectively made into the dilution and effective chlorine density that effective bromine is 1ppm
Liquor natrii hypochloritis carries out killing test to blue-green algae respectively, and experimental result is as follows：
