Abstract
The invention discloses the preparation methods for the magnetic green material function Carbon fibe being catalyzed based on light Fenton, using biological material as raw material, plant fiber is extracted by hydro-thermal process, using charing, poly-dopamine modification and ferroso-ferric oxide and titanium dioxide nano-particle load, the Carbon fibe of functionalization is obtained.Magnetic green material function Carbon fibe produced by the present invention includes Carbon fibe and the ferriferrous oxide nano-particle and titanium dioxide nano-particle in situ being carried on Carbon fibe, present invention can apply to light Fenton handle waste water, have many advantages, such as low raw-material cost, preparation method simply and can magnetic recovery, high treating effect during handling waste water.
Description
Technical field
The present invention relates to Carbon fibe Material Fields, more particularly to the magnetic green material function Carbon fibe based on the catalysis of light Fenton
And its preparation method and application.
Background technique
Activated carbon fibre is big with its contact area, specific surface area is high, adsorption capacity is big, adsorption/desorption rate is fast, heat-resisting resistance to
The advantages that soda acid, is widely used in the side such as the depollution of environment, catalyst carrier, electrode material as a kind of novel adsorption functional material
Face.And using Carbon fibe as nano titanium dioxide photocatalyst carrier, organic wastewater is handled, it is efficient can not only to play Carbon fibe
Absorbing synergic effect, effectively improve titanium dioxide to the Photocatalytic Degradation Property of organic pollutant, moreover it is possible to solve nanoscale two
The immobilized and losing issue of titanium oxide is widely used in handling organic pollutant wastewater.However just with Carbon fibe photocatalysis
The photocatalysis of agent is limited to by light source and catalytic efficiency etc., it is difficult to extensive efficient process organic pollutant wastewater.In conjunction with light
The light Fenton catalytic degradation technology of catalysis and Fenton's reaction, because its treatment process is without secondary pollution and H2O2Dosage is reduced, cost drop
It is low, can efficient degradation it is toxic/used water difficult to degradate, thus obtain in-depth study.Therefore, design has excellent catalytic degradation
The Carbon fibe light fenton catalyst of energy is particularly significant for efficient process Organic Pollutants in Wastewater.But micron order active carbon simultaneously
Still there is cost problem in the preparation of fiber optic fenton catalyst and its application in the water process depollution of environment, and actually answer
With in the process, the reclaimer operation of micron order light fenton catalyst can also further increase cost of water treatment.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, provide one kind using biological material as fiber
The magnetic green material function Carbon fibe of raw material preparation has many advantages, such as that low in cost, preparation method is simple and possesses and magnetic can return
Receipts and light Fenton catalysis, can apply to the processing of waste water.
In order to solve the above technical problems, the invention adopts the following technical scheme:
