Description
Technical field
The invention belongs to the water purification agent preparing technical field, relate to a kind of water purification agent and preparation method thereof.
Background technology
In most of purifiers a few days ago, all only adopt separately active carbon to come some noxious materials in adsorbed water as sorbing material.But single active carbon water purification agent can not be reused, and active carbon can affect the colourity of water, and pulverous active carbon is difficult for filtering simultaneously, is easy to cause secondary pollution.Usually active carbon is used for adsorbing micromolecular organic impurities, and its adsorption effect to the macromolecule organic that exists in water is poor.
Summary of the invention
In view of above problem, the invention provides a kind of diatomite is combined water purification agent of host material and preparation method thereof, the granular material that diatomite combines with active carbon and forms, not only kept the adsorption capacity of active carbon to fluorescence probe in water, and having overcome single powdered active carbon can exert an influence to colority of water, and be difficult for the problem such as filtration, combine especially the ability of macromolecule organic in diatomaceous adsorbed water.
The present invention relates to a kind of water purification agent, it comprises: the diatomite of mass fraction in the 6.25%-75.95% scope, the active carbon of mass fraction in the 1.10%-86.96% scope, and the sodium salt of mass fraction in the 2.22%-82.42% scope.
Further, the method for the above-mentioned water purification agent of preparation that the present invention relates to can also have such feature, comprises the steps:
A. diatomite and active carbon are mixed according to mass ratio 1:1-15:1, make mixture;
B. get a certain amount of mixture and join in dilute acid soln, make the mixed liquor I;
C. sodium hydroxide solution and absolute ethyl alcohol are mixed according to mass ratio 1:20-1:40, make the mixed liquor II;
D. with the mixed liquor I, fully stir, splash in described mixed liquor II, make the consolidation liquid that contains bead;
The consolidation liquid that e. will contain bead filters and obtains bead, and at room temperature air-dry after bead is washed with distilled water, obtains air-dry bead;
F. with air-dry bead continuous drying 5 hours in 80 ℃ of baking ovens, obtaining water purification agent, is the granular mixture of diatomite and active carbon for main component;
Wherein, the mass ratio of the acid in dilute acid soln and mixture is 1:3-1:5.
Further, the method for preparing water purification agent that the present invention relates to can also have such feature, and in step b: diluted acid can be any one in hydrochloric acid, sulfuric acid, phosphoric acid, acetic acid, and the concentration of diluted acid is the 1.0%-10.0%(mass fraction).
Further, the method for preparing water purification agent that the present invention relates to can also have such feature, and in step c: the concentration of described sodium hydroxide solution is the 20%-50%(mass fraction).
Effect of the present invention and effect:
A kind of combined water purification agent provided by the invention, take diatomite as host material, combine with active carbon, not only kept the adsorption capacity of active carbon to small molecule organic compound in water, and add due to diatomaceous, therefore macromolecule organic in all right adsorbed water can reach better combined adsorption effect.Simultaneously, water purification agent of the present invention has not only overcome the impact that single powdered active carbon water purification agent produces colority of water, therefore also having solved the shortcoming that single powdered active carbon is difficult to filter, can not cause secondary pollution, is the water-purifying material of a kind of efficient, cleaning, safety.
A kind of combined water purification agent of the present invention, usually through can Reusability after the drying of 50 ℃-80 ℃, therefore this combined water purification agent has wide prospect in the drink water purifying field.
The specific embodiment
Below in conjunction with specific embodiment, combined water purification agent of the present invention and preparation method thereof is described in detail.
