Abstract
The invention relates to a preparation method of an adsorbent for removing polar organic pollutants. The adsorbent can effectively adsorb small-molecule polar organic pollutants in water. The preparation method comprises the following steps: 1) crushing: crushing high-grade zeolite to 0.1-0.2mm granules; 2) sintering: continuously adding the zeolite granules into a rotary kiln, and sintering at 600 DEG C for 120-180 minutes to activate the zeolite granules; 3) modification: filling the sintered activated zeolite into a reaction kettle, and modifying in an 8 wt% sodium hydroxide and 2 wt% sodium metalluminate solution at 100-105 DEG C for 5-6 hours; 4) water washing: washing the modified zeolite with deionized water until the pH value is 8; and 5) drying: drying at 100-120 DEG C until the water content is 3-5%.
Description
Technical field
The present invention relates to the adsorbent that water depth is processed, especially a kind of preparation method who removes the agent of polarity Adsorption of Organic.
Background technology
At present, the adsorbent that is applied in the water depth processing mainly is active carbon, and its function is that the organic pollution in the water is had certain Adsorption effect, but active carbon can not adsorb little molecular polarity organic matter, and price is more expensive, thereby has affected its popularizing action in water depth is processed.
Summary of the invention
In order to overcome the shortcoming of acticarbon, the object of the present invention is to provide a kind of preparation method who removes the agent of polarity Adsorption of Organic, this adsorbent is the little molecular polarity organic pollution in the adsorbed water effectively.
A kind of preparation method who removes the agent of polarity Adsorption of Organic of the present invention may further comprise the steps:
1. broken step: the high-grade zeolite is crushed to the 0.1mm-4mm particle;
2. sintering step: zeolite granular was put in the stove of revolution cellar for storing things under 550 ℃ of-700 ℃ of temperature the sintering activation 120 minutes-180 minutes continuously;
3. modification procedure: the active zeolite behind the sintering is contained in the reactor, and with the NaOH of quality 6%-10% and the sodium aluminate solution of 2%-4%, modification is 5 hours-8 hours under temperature 95%-105%;
4. water-washing step: it is 8 that the zeolite after the modification cleans to pH value with deionized water;
5. drying steps: under 100 ℃-150 ℃ of temperature, be dried to water content 2%-5%.
The specific embodiment
Following embodiment is for the more detailed the present invention of explanation, is confined to this but should not be construed as the present invention.

3. modification procedure: the active zeolite behind the sintering is contained in the reactor, and with the NaOH of quality 8% and 2% sodium aluminate solution, modification is 5 hours-6 hours under temperature 100%-105%;
4. water-washing step: it is 8 that the zeolite after the modification cleans to pH value with deionized water;
5. drying steps: under 100 ℃-120 ℃ of temperature, be dried to water content 3%-5%.
Embodiment 2:
Be prepared according to a kind of preparation method who removes the agent of polarity Adsorption of Organic among the embodiment 1, only change the following parameter of embodiment 1 following steps.
Broken step: the high-grade zeolite is crushed to the 1mm-3mm particle;
Sintering step: zeolite granular was put in the stove of revolution cellar for storing things under 650 ℃ of temperature the sintering activation 120 minutes-180 minutes continuously;
More than design is only for explanation the present invention's, and be not to be limitation of the present invention, the those of ordinary skill in relevant technologies field, in the situation that does not break away from the spirit and scope of the present invention, other variation of having done and the technical scheme that all are equal to also should belong to category of the present invention.
