Technical field
The present invention relates to a kind of purification of water quality magnetic response type nucleocapsid photochemical catalysts and preparation method thereof, belong to material preparation
Field.
Background technique
Water environment is a part in ecological environment, and water pollution constitutes a serious threat to human survival and development.According to system
It counts, the pollution in water body is mainly derived from organic pollutant, such as chloroform, insecticide, halogenated aliphatic hydrocarbon.It is directed at present
The organic pollutant processing technique of water body mainly has biologic treating technique, materialization technology, chemical oxidation and catalytic oxidation technologies.
Conventional processing method there are removal efficiency it is low, selective, running expense is high the disadvantages of.Therefore in field of water quality purification,
Have the characteristics that the catalysis material that redox ability is strong, without secondary pollution provides one entirely for the degradation of organic pollutant
New approach.
The bismuth rich reserves in China, bismuth based material generally have low toxicity, inexpensive characteristic, unique outer-shell electron configuration
(6s2), keep the forbidden bandwidth of its compound relatively narrow, there is preferable visible light absorption capacity, be of considerable interest in recent years,
What is be widely studied at present has Bi2O3、Bi2WO6、Bi2O2CO3, BiOX etc..Wherein, BiOX (X=Cl, Br, I) unique stratiform
Structure and indirect transition mode are conducive to the transition of photo-generate electron-hole pairs, show excellent photocatalysis characteristic.With it is traditional
For catalysis material as titanium dioxide, zinc oxide, the development of BiOX encounters two main bottlenecks.First is that electron-hole recombinations
Rate is high, causes the utilization rate of solar energy low, catalytic efficiency is not high.Second is that separation and recovery problem, catalysis material is mostly powder, in water
It is generally difficult to recycle in matter purification, is not only difficult to recycle and makes full use of its catalytic, be more likely to cause secondary pollution to environment.Cause
This exploitation has visible light-responded novel photocatalyst, improves its photocatalytic activity by modification, compound means, adopts simultaneously
Powder, which will be catalyzed, with certain technology is carried on the immobilized hot spot for becoming research of realization catalyst on suitable carrier.
Li Lings etc. use hydro-thermal method with Fe in a kind of Core-shell magnetic composite microspheres and preparation method and with disclosing on the way3O4, nitric acid
Copper, trimesic acid, graphene oxide are that raw material is prepared for a kind of Core-shell magnetic composite microspheres and is applied to quickly processing waste water from dyestuff.Woods
Know gorgeous wait and discloses a kind of preparation method of magnetic core-shell alginate microsphere adsorbent in the patent of CN104707575A, it should
Method is prepared for a kind of magnetic core-shell alginate microsphere absorption using high-pressure electrostatic spinning equipment under high-pressure electrostatic injection conditions
Agent is applied to absorption enrichment anion and its wastewater treatment.The above method is all selected with Fe3O4For magnetic carrier, so that in Water Quality Office
The separation and recovery of material becomes more convenient during reason, but hydro-thermal and high-pressure electrostatic spinning equipment higher cost, realize it is low at
This large-scale production is more difficult.
Summary of the invention
It is an object of that present invention to provide a kind of low costs to prepare magnetic coupling BiOX catalysis material and its preparation side
Method.
The technical scheme is that using commercialization nano ferriferrous oxide as magnetic core, it is molten in alcohol using BiOX substance
Self assembly performance in liquid, immersion method directly prepare the hud typed catalysis material with magnetic responsiveness.Nano ferriferrous oxide exists
It while catalyst magnetism is provided, can act synergistically with BiOX, improve catalytic efficiency.Specifically comprise the following steps:
1. weighing 2mM Bi (NO3)3·5H2O, 8.5mL ethylene glycol, 17mL ethyl alcohol, are placed in container, mechanical stirring
30min, until dissolution is abundant.
2. the nano ferriferrous oxide that 1mM~6mM is added makes its dispersion using the intermittent ultrasound of ultrasonic cell disrupte machine
Uniformly；
3. configuring KI, KBr mixed solution that toatl proportion is 2mM, it is molten that mechanical stirring while, is added dropwise to above-mentioned mixing dropwise
Liquid adjusts solution acid alkalinity to neutrality using weak aqua ammonia.
4. above-mentioned solution is transferred in water-bath, 80 DEG C of reaction 3h, wash by washing, alcohol, is done in 40 DEG C of baking ovens later
Dry 12h obtains powder-product.
Step 1. in, the volume ratio of ethylene glycol and ethyl alcohol is 1/2.
Step 2. in, the partial size of nano ferriferrous oxide is 200-300nm.
Step 2. in, intermittent ultrasound is carried out to mixed solution using ultrasonic cell disrupte machine, is divided into 30s, it is super every time
Sound 20s continues 15 times.
Step 3. in, the control of the molar ratio of KBr, KI is between 1/4 to 2/3.
Step 3. in, the rate of addition of solution need to be maintained at 1mL/min.
Step 3. in, pH is adjusted to by neutrality by weak aqua ammonia.
Compared with prior art, the present invention have the advantages that significant be:
1, in catalytic process, catalysis material is not easy to fall off with magnetic core, and repeatedly after circulation, catalytic efficiency still is able to maintain
90% or more.
2, preparation cost is low, is not required to introduce the inert inorganic oxide of photochemistry as nucleocapsid middle layer；Preparation temperature is low,
The condition of 80 DEG C of water-baths is suitble to the large-scale production of catalyst.
3, under visible light, which shows good light degradation effect for phenol
