Description
Technical field:
This hair is related to a kind of preparation method of synthetic, more particularly to the preparation method of titanium dioxide absorption activated carbon synthetic.
Background technique
Due to industrial wastewater, a large amount of discharges of chemical products, consuming excessively caused by the mankind gets worse seawater
Pollution.Pollutant in seawater includes drug, pesticide, organic dyestuff and phenols etc..Even if the concentration of these pollutants is very low,
But due to its toxicity, serious harm has been had resulted in the ecosystem.Wherein the antibiotic in drug is in addition to for treating
Other than prevention disease, it is also heavily used in aquaculture and animal husbandry, and environment water is entered by sewage treatment plant, at
For an increasingly severe problem, natural environment is endangered.Wastewater treatment method traditional at present not can solve these dirts
The problem of contaminating object, so solution is badly in need of to reduce the content of antibiotic in China.
Summary of the invention:
To solve the above-mentioned problems, the present invention provides titanium dioxide absorption activated carbon synthetic, activated carbon adsorption and in titanium dioxide
Three aspects of photocatalytic degradation and auto-degradation under the action of titanium, reaching reduces organic pollutants content.
The purpose of the present invention is aiming at the shortcomings in the prior art, provide a kind of titanium dioxide absorption activated carbon synthetic
Preparation method, including the following steps:
(1) 10-50g titanium tetraisopropylate is dissolved in 20-30ML, stirs 30-50 minutes, mixes them thoroughly.
(2) 300ML ethanol solution is added dropwise in mixture, and continues stirring 30-50 minutes, until mixture is in clear
Clear uniform colloidal sol and start to occur muddy.
(3) active carbon and mixture are put into togerther in magnetic stirrer and are stirred and evaporate moisture content, the matter of active carbon
Amount ratio is 10%-90%, carries out adding water and stirring hydrolysis 3-5 hours, mixture is allowed to gradually form precursor gel shape.
(4) gelatinous mixture is placed into the controllable flow rate baking oven that heating speed is 4 DEG C/min under nitrogen atmosphere,
Precursor gel mixture is heated to 773k.
(5) the mixture natural cooling after heating is closed to get to the titanium dioxide absorption activated carbon in more empty grey shapes
At object, preservation is dried.
As preferred: in the step (1), 20g titanium tetraisopropylate being dissolved in 30ML, is stirred 30 minutes, makes it sufficiently
Mixing.
As preferred: in the step (2), 300ML ethanol solution being added dropwise in mixture, and continues 30 points of stirring
Clock, until mixture in clear uniform colloidal sol and starts to occur muddy.
As preferred: in the step (3), the mass ratio of active carbon is 10%, 50%, 90%, and is added water and stirred
Hydrolysis 5 hours.
The present invention three aspects of photocatalytic degradation and auto-degradation using activated carbon adsorption and under the action of titanium dioxide,
Reach reduce organic pollutants content the features such as.
Specific embodiment
Below with reference to specific implementation example, the present invention is described in detail:
A kind of preparation method of titanium dioxide absorption activated carbon synthetic, including the following steps:
(1) 10-50g titanium tetraisopropylate is dissolved in 20-30ML, stirs 30-50 minutes, mixes them thoroughly.
(2) 300ML ethanol solution is added dropwise in mixture, and continues stirring 30-50 minutes, until mixture is in clear
Clear uniform colloidal sol and start to occur muddy.
(3) active carbon and mixture are put into togerther in magnetic stirrer and are stirred and evaporate moisture content, the matter of active carbon
Amount ratio is 10%-90%, carries out adding water and stirring hydrolysis 3-5 hours, mixture is allowed to gradually form precursor gel shape.
(4) gelatinous mixture is placed into the controllable flow rate baking oven that heating speed is 4 DEG C/min under nitrogen atmosphere,
Precursor gel mixture is heated to 773k.
(5) the mixture natural cooling after heating is closed to get to the titanium dioxide absorption activated carbon in more empty grey shapes
At object, preservation is dried.
Column are preferably implemented: in the step (1), 20g titanium tetraisopropylate being dissolved in 30ML, stirs 30 minutes, fills it
Divide mixing.
Column are preferably implemented: in the step (2), 300ML ethanol solution being added dropwise in mixture, and continue stirring 30
Minute, until mixture in clear uniform colloidal sol and starts to occur muddy.
Column are preferably implemented: in the step (3), the mass ratio of active carbon is 10%, 50%, 90%, and carries out that water is added to stir
Mix hydrolysis 5 hours.
