The organic substances such as element.These materials, can be by the biological chemistry action of microorganism to suspend or dissolved state is present in sewage
And decompose.Need to consume oxygen in its decomposable process, thus be referred to as oxygen consumption pollutant.This pollutant can cause molten in water
Solve oxygen to reduce, the growth of influence fish and other aquatiles.After oxygen in water exhausts, organic matter carries out anaerobic digestion, production
The bad smells such as raw hydrogen sulfide, ammonia and mercaptan, make water quality deterioration.
With the development of production, the murder by poisoning organic pollution produced in industrial and agricultural production seriously threatens environment and people
The health of class, seeks a kind of new and effective environmental improvement technology and has great importance.Photocatalysis technology is because of its energy-conservation, height
Effect, contaminant degradation are thorough, non-secondary pollution advantage, turn into a kind of emerging environmental improvement with important application prospect at present
Technology.In recent years, the development of new and effective visible-light photocatalyst turns into an important research content in photocatalysis technology.
In June, 2010, material research institution researcher has found that silver orthophosphate has the effect of photochemical catalyst, and photooxidation effect is
It is more than the decades of times for being currently known various photochemical catalysts.Because its unique Surface Physical Chemistry property and efficient visible ray light are urged
Change one of performance, focus as research.
But nanoparticles are easily reunited, surface area is greatly reduced after reunion, decreased effectiveness.Need to use appropriate carrier
Or change catalyst macrostructure to obtain preferable catalytic effect.
The content of the invention
The purpose of the present invention be for overcome in the prior art particulate matter be easy to reunion and cause effect difference etc. not enough there is provided one kind
The preparation method of silver phosphate photocatalyst film.
The technical solution adopted by the present invention is in turn include the following steps:
1) 20~24mmol silver nitrates are weighed, 20mmol/L silver nitrate solution is configured to, 6.6~8mmol phosphoric acid is weighed
Disodium hydrogen, is configured to 20mmol/L disodium phosphate soln;
2) both the above solution is mixed under 350~400 revs/min of rotating speed, forms yellow green colloid substance, continued
3~4h is stirred, disodium hydrogen phosphate and silver nitrate reaction, generate phosphoric acid silver colloid in whipping process;
3) it is 10~30cm by area2Quartz glass horizontal positioned, phosphoric acid silver colloid brush is dipped with brush in quartzy glass
The side surface of glass one, one layer of brush again after drying naturally, then one layer of brush, brush 4~5 times altogether, in quartz glass again after drying naturally
One side surface obtains thin layer phosphoric acid Argent grain;
4) quartz glass is placed on above the kerosene lamp flame of burning and toasted, covered with silver orthophosphate facing to flame,
Until covering carbon nano-particle in phosphoric acid silver surface, a kind of silver phosphate photocatalyst film is made.
The beneficial effects of the invention are as follows:
1. the concentration of strict control disodium hydrogen phosphate and silver nitrate advantageously forms silver orthophosphate in 20mmol/L during being somebody's turn to do
Colloid, rather than silver orthophosphate precipitation, colloid are stable in water, will not precipitate, and are conducive in Quartz glass surfaces formation silver orthophosphate
Film.
2. covering one layer of carbonaceous membrane in silver orthophosphate film surface, electron transmission can be accelerated, preferably degraded effect is obtained
Really.
