The invention provides a preparation method of an extract for degrading triphenyl and an triphenyl purifying agent, which are suitable for treating indoor air pollution after decoration.
The invention provides a preparation method of an extract for degrading triphenyl, which comprises the following steps:
will be at 0.1mg/m3～0.5mg/m3Culturing the water chestnut in benzene concentration environment for 30-60 days and at 0.15mg/m3～0.65mg/m3Grinding the gazania cultured for 60-90 days in a toluene concentration environment to obtain a mixed ground substance;

Further, the specific steps of weighing isopropanol, adding the isopropanol into the mixed ground substance, and filtering to obtain a filtrate comprise:
weighing isopropanol, adding the isopropanol into the mixed ground substance, stirring for 30-60 min at the stirring speed of 300-500 rpm, and uniformly mixing;
filtering with filter membrane, and removing residue to obtain filtrate.
Specifically, the pore size of the filter membrane is 0.25 um.
Specifically, the mass ratio of the rhombus flower to the gazania is (0.5-5): 1.
In one embodiment, the preparation method of the extract for degrading triphenyl comprises the following steps:
weighing the whole plant of the specially cultured rhombohedral rhombus and gazania, and grinding to obtain a mixed ground substance;
adding isopropanol into the mixed ground product, wherein the mass ratio of the isopropanol to the mixed ground product is (8-12): 1;
putting the mixed ground substance and the isopropanol into a stirrer, and uniformly stirring for more than or equal to 30min at a stirring speed (300-500) rpm to obtain a mixed crude extract;
and filtering the mixed crude extract by using a filter membrane with the aperture of 0.25um, removing residues, and collecting filtrate to obtain the extract for degrading the triphenyl.
The invention also provides a triphenyl purifying agent, which comprises: degrading triphenyl extract, chloride, surfactant and preservative, wherein the solvent is water;
the mass percentages of the components are as follows:
10-30% of triphen degradation extract;
2-5% of chloride;
0.5-2% of a surfactant;
0.5-2% of a preservative;
the extract capable of degrading triphenyl is prepared by the preparation method of the extract capable of degrading triphenyl.
In the present example, in order not to cause secondary pollution to the purified air, the mixed extracts of rhombohedral rhombi and gazania were selected to provide proteases for decomposing triphenyl substances by degrading protease secreted from the extract of triphenyl (which was prepared by the preparation method of the extract of degraded triphenyl) without causing secondary pollution. And the selected water chestnut is obtained in a benzene culture environment, the secreted protease can more effectively realize the decomposition of benzene, the selected gazania medallion is obtained in a toluene culture environment, and the secreted protease can more effectively realize the decomposition of toluene and xylene substances, so that the air purifying agent prepared by using the plant extracts cultured by the water chestnut and the gazania medallion in a special culture environment can more efficiently decompose the triphenyl substances in the indoor air.
Meanwhile, in order to improve the quality of the protease and the activity of the protease, chloride is added. And through the combination of chloride ions on cell membranes, the protease enters the intercellular solution from the cytoplasmic solution more smoothly, so that the protease is gathered in the intercellular solution, and the inhibition effect caused by overhigh concentration of the protease in the cytoplasmic solution is avoided. Thus, the activation of an enzyme system inside cells of the water chestnut and the gazania gazanioides is realized, so that the yield of the protease is improved, the decomposition efficiency of the protease is improved, and the purification effect of the triphenyl purifying agent is greatly optimized.
Meanwhile, in order to reduce the propagation of microorganisms in the triphenyl purifying agent and reduce the secondary pollution of indoor air, the preservative is added. In addition, the addition of the preservative can also reduce the decomposition of the protease by the microorganisms, and further maintain the capability of removing pollutants of the triphenyl purifying agent.
The purifying agent liquid is added with surfactant for better atomization effect when the purifying agent liquid is discharged from the bottle mouth. The surfactant enables the liquid from the nozzle to be more uniformly dispersed into finer particles, greatly improves the dispersion degree of the purifying agent in the indoor air, and enlarges the contact area of the purifying agent and the air.
Further, the chloride is one or the combination of magnesium chloride, zinc chloride and calcium chloride. The surfactant is sodium dodecyl sulfate. The preservative is potassium sorbate.
In one embodiment, the chloride is calcium chloride.

and 2) respectively weighing 2-5 g of chloride, (0.5-2) g of surfactant and (0.5-2) g of preservative, sequentially adding the chloride, (0.5-2) g of surfactant and (0.5-2) g of preservative into the extract for degrading the triphenyl (1), adding water to 100g, and uniformly mixing to obtain the triphenyl purifying agent.
From the above, in step 1), in order to achieve the optimal biological purification effect and not bring secondary pollution to indoor air, the mixed extract of the rhombus and gazania is selected as the extract for degrading the triphenyl. Specifically, in the step 2), the extract of the degraded triphenyl, the chloride, the surfactant and the preservative are uniformly mixed by adopting a stirring and uniformly mixing mode, and the stirring is carried out for 10min at the stirring speed of (300-500) rpm.
The application method of the triphenyl purifying agent prepared by the preparation method of the triphenyl purifying agent comprises the following steps: and (3) taking a proper amount of the product of the triphen purifying agent in a sprayer/sprayer, uniformly spraying the triphen purifying agent to an indoor area needing air purification by using the sprayer/sprayer, and spraying for 1-5 times to complete the purification of indoor air, wherein the whole process is convenient, simple and easy to operate.
In order to better illustrate the purifying effect of the triphenyl scavenger in the present invention, the following examples of specific components are selected as references in the present invention.
The experimental data for the example groups are given in the following table:
referring to national standard QB/T2761-2006 method for determining purification effect of indoor air purification product, two 1m samples are used3The climate chamber (A is a blank chamber, and B is a test chamber) tests the purifying effect of the invention on the pollutants such as benzene, toluene, xylene and the like in the air. Equal amounts of contamination sources were charged to both climatic chambers and 5 ml of the reagent of the invention was sprayed evenly into chamber B. After 24 hours and 168 hours, the concentration of the pollutant in A, C0, and the concentration of the pollutant in B, C1, were measured, and the pollutant removal rate was calculated according to the following formula:
the results of the test for purifying the triphenyl substance using the triphenyl scavenger disclosed in the present application in the above example group are shown in table 1 below (table 1 is data of the purification results and purification effects of the triphenyl scavenger after 24 hours of action in one example of the present invention):
table 1:
the cleaning effect after 24 hours of the above example group shows: the triphen degradation extract plays a decisive role in purifying the triphen purifying agent to the triphen substances in the embodiment of the invention, and the triphen purifying agent has a greatly improved removing rate to the triphen substances along with the increase of the specific gravity of the triphen degradation extract in the triphen purifying agent; when the number of the benzene three-benzene purifying agent is a certain value (the mass of the benzene three-benzene degrading extract is 20g per 100g of the benzene three-benzene purifying agent), the removing rate of the benzene three-benzene purifying agent to benzene three-benzene substances is gradually reduced along with the further increase of the specific gravity of the benzene three-benzene degrading extract in the benzene three-benzene purifying agent. The calcium chloride has an obvious positive effect on the removal rate of the triphenyl substances, and the removal rate of the triphenyl substances is greatly improved along with the improvement of the specific gravity of the calcium chloride in the triphenyl purifying agent; when the triphenylpurifying agent reaches a certain value (the mass of the calcium chloride is 5g per 100g of the triphenylpurifying agent), the removing rate of the triphenylpurifying agent on the triphenylmatters is greatly reduced along with the further increase of the specific gravity of the calcium chloride in the triphenylpurifying agent. The surfactant has a certain positive effect on removing the triphenyl substances, and the removing rate of the triphenyl purificant on the triphenyl substances is improved slightly along with the improvement of the specific gravity of the surfactant in the triphenyl purificant; when the amount of the triphenylpurificant reaches a certain value (the mass of the surfactant is 2g per 100g of the triphenylpurificant), the removal rate of the triphenylpurificant to the triphenylmaterial is reduced slightly along with the increase of the specific gravity of the surfactant. The removal of the triphenyl substances by the potassium sorbate has little influence, but when the content of the potassium sorbate exceeds a certain value (the mass of the potassium sorbate per 100g of the triphenyl scavenger is 2g), the removal rate of the triphenyl scavenger on the triphenyl substances decreases as the specific gravity of the potassium sorbate increases.
Specifically, when the amount of the triphenyl degradation extract in 100g of the triphenyl scavenger is 20g, the amount of the calcium chloride in 100g, the amount of the surfactant in 2g, and the amount of the potassium sorbate in 2g, the triphenyl scavenger achieves the optimal purification effect, and at this time, the benzene removal rate reaches 83.4%, the toluene removal rate reaches 84.4%, and the xylene removal rate reaches 70.6%.
Further, the results of the test for the purging of the triphenyl substance using the triphenyl scavenger as claimed in the present application in the above example group are shown in table 2 below (table 2 is data of the purging result after 168 hours of the action of the triphenyl scavenger in one example of the present invention and the purging effect thereof):
table 2:
the cleansing effect after 168 hours combined with the cleansing effect at 24 hours for the above example group indicates that: the longer the time that the triphenyl purifying agent is sprayed in the room, the higher the removing rate of the triphenyl substance in the indoor air, and the better the purifying effect on the indoor air. Under the optimal mixture ratio, the removal rate of benzene reaches 86.5%, the removal rate of toluene reaches 86.4%, and the removal rate of xylene reaches 78.5%.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the scope of the present invention; all equivalent changes made within the scope of the claims of the present invention are covered by the claims of the present invention.
