Abstract
The present invention discloses a kind of with capillarity silver phosphate photocatalyst preparation method, it in turn includes the following steps: 1) silver wire that diameter is 0.1~2.0mm being dipped in 5~10min of hydrogen peroxide that mass concentration is 30%, taking-up is rinsed 3~5 times with deionized water, it is dipped in 20~40min in the phosphoric acid solution that mass concentration is 1%~20% again, it takes out, is washed with deionized water 3~5 times；2) treated 2~4 bursts of silver wires and 6~10 strands of macromolecular fibres are woven into line, then these lines with being woven into cloth to get to capillarity silver phosphate photocatalyst.Using the hydrophily and knitting wool characteristic of fiber, it is formed on its surface film, the thorough degradable organic pollutant under solar radiation.The present invention is applicable in and motorless organic wastewater treating system.
Description
Technical field
The present invention relates to the exploitations of novel environmental pollution control material, more particularly to one kind, and there is capillarity silver orthophosphate light to urge
Agent preparation method.
Background technique
Catalyst carrier is 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 for supporting active component, and catalyst is made to have specific physical behavior, and carrier itself does not have generally
There is catalytic activity.Majority carrier is the product in Catalyst, and there are commonly alumina support, silica-gel carrier, carried by active carbon
Body and certain natural products such as float stone, diatomite etc.." active component title-container name " is commonly used to show loaded catalyst
Composition, such as plus vanadium oxide-diatomite catalyst of the nickel-alumina catalyst of hydrogen, oxidation.Pass through the side such as ion exchange
Some compounds are introduced interlamination region by formula, form the other pillar of molecular level, and manufactured one kind aperture is big, novel point distribution rule
The horizontal composite material of son has the characteristics that absorption, conversion organic molecule.Hydrotalcite is wide in variety, and the adjustability of pillar compound changes
Clay material pore size, adsorption property after property etc. can taking human as being controlled, therefore can difference depending on the application come into
The preparation of row material, has wide application prospects in numerous areas such as petrochemical industry, environmental protections.
Carrier can make manufactured catalyst have suitable shape, size and mechanical strength, to meet industrial reactor
Operation requires；Carrier can make active component dispersion on the surface of the carrier, obtain higher specific surface area, improve unit mass activity
The catalytic efficiency of component.
Photochemical catalyst is applied in the processing such as organic pollutant decomposition as a kind of novel environment-friendly treatment method.
But nanometer chicken catalyst material has the shortcomings that its is intrinsic i.e. during use: easy to reunite, it is therefore desirable to is carried on load
Body surface face is to obtain optimal using effect.There is a problem of that separation is difficult after catalytic action, if to be separated clean, need through
Multiple steps are crossed, it is time-consuming and laborious.
Summary of the invention
The purpose of the present invention is provide a kind of with capillary to overcome the shortcomings of photocatalyst technology in the prior art
Act on silver phosphate photocatalyst preparation method.
The technical solution adopted by the present invention is that in turn including the following steps:
1) silver wire that diameter is 0.1~2.0mm is dipped in 5~10min of hydrogen peroxide that mass concentration is 30%, taking-up is spent
Ionized water rinses 3~5 times, then is dipped in 20~40min in the phosphoric acid solution that mass concentration is 1%~20%, takes out, uses
Deionization is washed 3~5 times；
2) treated 2~4 bursts of silver wires and 6~10 strands of macromolecular fibres are woven into line, then these lines with being woven into
Cloth is to get to capillarity silver phosphate photocatalyst.
The invention has the advantages that using silver wire be formed on its surface oxide layer and then and phosphatase reaction, formed phosphoric acid
Silver.There are the silver wire of silver orthophosphate and macromolecular fibre to be spun into after line load and be made into cloth again, i.e., using the hydrophily of fiber and hair
Line characteristic, is formed on its surface film, the thorough degradable organic pollutant under solar radiation.The present invention is applicable in be had with motorless
Machine waste water treatment system.
