[0026] The embodiment of the present invention discloses a method for preparing a permeate, comprising the following steps: mixing an acidic palladium salt solution, a solvent and polyvinylpyrrolidone (PVP), and stirring to obtain the first mixed solution; adding the orthosilicate solution dropwise into the first mixed solution, and then statically aged after stirring to obtain a second mixed solution; adding phosphomolybdic acid and preservatives to the second mixed solution dropwise, and obtained a permeate after stirring.
[0027] According to the present invention, the solvent is preferably a hydrophilic solvent with 2-8 carbon atoms; the orthosilicate is ethyl orthosilicate, methyl orthosilicate or propyl orthosilicate. The preferred amount of raw materials in the permeate is as follows:
[0028]
[0029] More preferably, the amount of raw materials in the permeate is as follows:
[0030]
[0031] More preferably, the amount of raw materials in the permeate is as f...
Embodiment 1
[0061] The fresh-cut flowers selected in this embodiment are white gardenias. The preservative ethyl p-hydroxybenzoate was purchased from Zhengzhou Lvbo Chemical Products Co., Ltd.
[0062] A kind of preserved flower with carbon monoxide warning function, its preparation method is as follows:
[0063] 1) Washing and arranging the fresh cut flowers, placing them in ethanol for dehydration for 24 hours, to remove the interstitial fluid in the cut flower cells, adding a small amount of molecular sieves to the dehydrating agent to improve the water removal efficiency;
[0064] 2) Soak the dehydrated fresh cut flowers in the permeate at room temperature for 24 hours;
[0065] 3) Arrange the infiltrated fresh cut flowers to remove surface liquid, and place them in an oven at 50° C. for slow drying.
[0066] The preparation method of above-mentioned permeate is as follows:
[0067] 1) Dissolve 0.2 g of palladium chloride with 0.5 ml of 15% hydrochloric acid, add 17.5 ml of ethanol...
Embodiment 2
[0073] The fresh cut flower that present embodiment selects is pink camellia. The preservative potassium sorbate was purchased from Ningbo Wanglong Group Co., Ltd., and polyethylene glycol (PEG) was purchased from Sinopharm Reagent.
[0074] A kind of preserved flower with carbon monoxide warning function, its preparation method is as follows:
[0075] 1) washing and arranging the fresh cut flowers, placing them in n-butanol for dehydration for 24 hours, to remove the interstitial fluid in the cut flower cells, and adding anhydrous calcium chloride to the dehydrating agent to improve the water removal efficiency;
[0076] 2) Soak the dehydrated fresh cut flowers in the permeate at room temperature for 24 hours;
[0077] 3) Arranging the infiltrated fresh cut flowers to remove surface liquid, and placing them in an oven at 55° C. for slow drying.
[0078] The preparation method of above-mentioned permeate is as follows:
[0079] 1) Dissolve 0.5 g of palladium chloride with 0...
