Specific implementation mode
It in order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below will be in the embodiment of the present invention
Technical solution be clearly and completely described.The person that is not specified actual conditions in embodiment, builds according to normal condition or manufacturer
The condition of view carries out.Reagents or instruments used without specified manufacturer is the conventional production that can be obtained by commercially available purchase
Product.
A kind of binary blend and preparation method for adsorbing coloring agent provided in an embodiment of the present invention is carried out below
It illustrates.
A kind of preparation method for adsorbing the binary blend of coloring agent, including：It is 8-12mg/ml's by mass fraction
The gelatin solution that chitosan solution and mass fraction are 8-12mg/ml is 1-4 according to additive amount:1-4 is dried after being blended；
Further, it is 2-3 according to additive amount by chitosan solution and gelatin solution：2-3 is blended；A more step, chitosan is molten
The additive amount of liquid and gelatin solution is 2：3, to obtain better adsorptivity.
Wherein, chitosan solution is also known as chitosan, is that the product of chitin deacetylation passes through β-D-1,4 glucosides
A kind of 2- acetylaminohydroxyphenylarsonic acids 2- deoxidations-D glucopyranose linear polymers made of key connection, abundance, it is not soluble in water and
Ordinary organic solvents have the characteristics that mechanicalness is good, chemical property is stablized.Chitosan is nontoxic, has multiple biological activities.
Chitosan antioxidant activity depends on its molecular weight and deacetylation, and with the increase of deacetylated degree, antioxidant activity is got over
By force.The antifungal activity and antimicrobial acivity of chitosan derive from its polycation characteristic, with a large amount of free protons of intramolecular
Change increasing for amino, making it dissolve property greatly improves, reactivity enhancing.Industry product are that white or linen translucent sheet are solid
Body, slightly pearly luster.It is practically insoluble in water, but is dissolved in organic acids such as formic acid, acetic acid, benzoic acid and aphthenic acids and dilute inorganic
Acid.From 1859, after Frenchman Rouget obtains chitosan first, the biological functionality and compatibility of this natural polymer,
The excellent performances such as blood compatibility, safety, microbic resolvability by all trades and professions extensive concern, medicine, food, chemical industry,
The application study of the numerous areas such as cosmetics, water process, METAL EXTRACTION and recycling, biochemistry and biomedical engineering achieves great
Progress.
In the present embodiment, the configuration of chitosan solution is not specifically limited, and includes further：By chitosan, volume
A concentration of 2% acetic acid solution and water is 0.8-1.2g according to additive amount：50ml：50ml mixing stands 0.4-0.6h.Specifically,
In the present embodiment, in order to obtain the more stable chitosan solution of performance, further, weigh in the balance take 1g chitosans in
In 100ml beakers, it is subsequently added into 2% acetic acid solution of 50ml, is gently mixed, and is slowly added into distilled water to 100ml, so
After stand 0.4-0.6h, to be fully swollen.Further, the additive amount of chitosan is 1g；The mass fraction of chitosan solution is
10mg/ml。
Gelatin is usually that raw material is made through hydrolysis using the collagen of the skin of animal and bone, by hydrolyzing three spiral of collagen
Structure is changed into the compatibility and the good protein of degradability that random chain obtains, as gelatin.Gelatin heats in water
Can dissolve to certain temperature form the gel for having favorable elasticity, while there is good compatibility and high dispersion etc. it is special
Property.But the mechanical property of materials made of natural material is poor.
In the present embodiment, the configuration of chitosan solution is not specifically limited, and includes further：Gelatin, volume is dense

Then absorbance change is measured again, records data, is measured twice, so that it may obtain the absorbance change curve of disperse blue 60-2, finally
Analysis keep a record as shown in Figure 1；
Fig. 1 the result shows that, with the increase of absorbing time, the binary blend that embodiment 2 and 3 provides is to disperse blue 60-2
Absorbance all first increase and reducing, and absorbing time is more long, and the variation of absorbance gradually tends towards stability value all than initial extinction
It spends small.In 20min, the absorbance of embodiment 2 reaches peak value；Reach peak value in the absorbance of 30min or so, embodiment 3.
Experimental example 2
Experimental method：Configuration quality score is 10-5Disperse red FB；Disperse red FB is first measured before experiment does not start to
Suction brightness, record data, be then separately added into the binary blend that embodiment 2 and 3 is prepared again, the suction measured at this time is bright
Degree；Then the absorbance change for the binary blend that embodiment 2 and 3 is prepared in the absorbance of disperse red FB is measured again：With
Disperse red FB is added to above the coverslip for the binary blend that embodiment 2 and 3 is prepared by rubber head dropper respectively, then molten
It is added in the instrument for being put into cuvette and surveying absorbance after solution 10min, wavelength is transferred to the maximum absorption wavelength of disperse red FB
At 521nm, it is reference to be then placed in distilled water, and the solution on coverslip is sucked colorimetric by three groups of one-shot measurement with rubber head dropper
In ware, a sample is measured every 10min, record data will increase after being measured as 1h, are 1h, then measure again interval time
Absorbance change records data, measures twice, so that it may obtain the absorbance change curve of disperse red FB, the analysis that finally keeps a record is shown in
Shown in Fig. 2；
Fig. 2 the result shows that, with the increase of absorbing time, the suction of binary blend that embodiment 2 provides to disperse red FB
Luminosity is gradually reduced last gradually stable；The binary blend that embodiment 3 provides, which first increases the absorbance of disperse red FB, to be subtracted
It is few finally to tend towards stability, and final absorbance value is all smaller than initial absorbance.The binary blend that embodiment 2 provides is de-
Calibration curve is obtained when color 10min；The binary blend that embodiment 3 provides obtains calibration curve in 20min.
In conclusion using the binary blend provided by the present invention for adsorbing coloring agent；The binary blend is to dye
Expect disperse blue 60-2 and disperse red FB have very with excellent adsorptivity.Using provided by the present invention for absorption coloring agent
