Abstract
The invention discloses a preparation method of a silver phosphate photocatalyst with capillary action. The preparation method comprises the following steps: 1) soaking silver threads with diameter of 0.1-2.0mm in 30% hydrogen peroxide by mass for 5-10min, taking out and washing with deionized water for 3-5 times; and soaking in 1-20% phosphoric acid solution by mass for 20-40min, taking out and washing with deionized water for 3-5 times; and 2) spinning threads from the treated 2-4 strands of silver threads and 6-10 strands of polymer fiber, and weaving cloth from the threads to obtain a silver phosphate photocatalyst with capillary action. Given the hydrophilcity and woolen yarn characteristic of fiber, a film is formed on the surface, and organic pollutants are thoroughly degraded under solar radiation. The preparation method disclosed by the invention is applicable to an unpowered organic wastewater treatment system.
Description
Technical field
The present invention relates to the exploitation of novel environmental pollution control material, more particularly to a kind of there is capillarity silver orthophosphate light to urge
Agent preparation method.
Background technology
Catalyst carrier, also known as carrier, is one of composition of loaded catalyst.Catalytic active component is supported on carrier table
On face, carrier is mainly used in supporting active component, makes catalyst have specific physical behavior, and carrier itself does not typically have
There is catalysis activity.Majority carrier is the product in Catalyst, and conventional has alumina support, silica-gel carrier, carried by active carbon
Body and some natural products such as float stone, diatomite etc..Commonly use " active component title-container name " to show loaded catalyst
Composition, the such as vanadium oxide-diatomite catalyst of the nickel-alumina catalyst of hydrogenation, oxidation.By the side such as ion exchange
Formula introduces interlamination region some compounds, forms the other pillar of molecular level, made by a class aperture it is big, new point of distribution rule
The horizontal composite of son, the characteristics of with absorption, conversion organic molecule.Hydrotalcite is wide in variety, the adjustability of pillar compound, changes
Clay material pore size, adsorption property after property etc. can artificially be controlled by, therefore can be entered according to the difference of purposes
Prepared by row material, have wide application prospects in numerous areas such as petrochemical industry, environmental protection.
Carrier can make made by catalyst there is suitable shape, size and mechanical strength, to meet industrial reactor
Operation is required；Carrier can be such that active component is dispersed on carrier surface, obtain higher specific surface area, improve unit mass activity
The catalytic efficiency of component.
Photochemical catalyst is applied as a kind of new environment-friendly treatment method in organic pollution decomposition etc. is processed.
But nanometer chicken catalyst material has the shortcomings that its is intrinsic i.e. during use：Easily reunite, it is therefore desirable to be carried on load
Body surface face is obtaining optimal using effect.There is a problem of separating difficulty after catalytic action, if to be separated clean, need Jing
Multiple steps are crossed, is wasted time and energy.
The content of the invention
The purpose of the present invention be to overcome the shortcomings of prior art in photocatalyst technology, there is provided one kind have capillary
Effect silver phosphate photocatalyst preparation method.
The technical solution used in the present invention is in turn include the following steps：
1) silver wire of a diameter of 0.1～2.0mm is dipped in into 5～10min of hydrogen peroxide that mass concentration is 30%, taking-up spends
Ionized water rinse 3～5 times, then be dipped in mass concentration be 1%～20% phosphoric acid solution in 20～40min, take out, use
Deionization is washed 3～5 times；
2) by process after 2～4 bursts of silver wires and 6～10 strands of macromolecular fibres be woven into line, then these lines with being woven into
Cloth, that is, obtain with capillarity silver phosphate photocatalyst.
It is an advantage of the invention that：Using silver wire after its surface forms oxide layer, then and phosphatase reaction, form phosphoric acid
Silver.The silver wire and macromolecular fibre that are loaded with silver orthophosphate are spun into after line and are made into cloth again, you can using the hydrophily and hair of fiber
Line characteristic, on its surface film, the thorough degradable organic pollutant under solar radiation are formed.The present invention is suitable for be had with motorless
Machine Waste Water Treatment.
Specific embodiment
