Embodiment 1
[0025] Embodiment 1 A kind of adsorption method of graphene oxide / fiber composite material A1
[0026] Present embodiment 1 provides a kind of adsorption method of graphene oxide / fiber composite material, and it is to take by weighing 50g GO and add in 5L water, be mixed with the GO aqueous solution that concentration is 10g / L, use concentration as 0.1mol / L dilute Hydrochloric acid adjusts the pH value to 5, adds 10g sodium chloride, makes the concentration of sodium chloride in the GO aqueous solution be 2g / L, then adds 4g polyester (the substrate here includes but not limited to cellulose fiber, acrylic fiber, polypropylene fiber, polyester fiber) , spandex; cellulose fibers include but not limited to natural fibers, chemical fibers, cotton yarns, hemp yarns, viscose threads, etc.), on a constant temperature water bath shaker, shake and mix for 40 minutes at 25°C, filter, and dry to obtain graphite oxide ene / fiber composites A1.
Embodiment 2～6
[0027] The adsorption method of embodiment 2~6 graphene oxide / fiber composite material A2~A6
[0028] Examples 2 to 6 respectively provide an adsorption method of graphene oxide / fiber composite material. The preparation method is basically the same as that of Example 1, except that some process parameters are different. The specific process parameters are shown in Table 1.

[0030]
[0031] Other processing parameters are all identical with embodiment 1.
Embodiment 7G
[0032] The adsorption rate of embodiment 7GO on the cellulose fiber
[0033] Take 10 mg of GO and add 100 mL of deionized water, and after ultrasonication in a 298K (25°C) water bath for 1 h, a uniformly dispersed GO stock solution is obtained, which is then diluted with deionized water to obtain concentrations of 10, 20, 30, 35, 40, 45 And 50mg / L brown-yellow GO standard solution.
[0034] Using a visible spectrophotometer to measure, it can be seen that the maximum absorption peak of GO in deionized aqueous solution is 307nm, and then respectively measure the absorbance of the corresponding brown-yellow GO standard solution to obtain the corresponding brown-yellow GO standard solution absorbance A, and draw the absorbance For the standard curve of A and concentration C, see figure 1 , the resulting linear regression equation is A=0.0071×C+0.0188, R 2 =0.9973, wherein the slope B of the linear relationship between absorbance and concentration is 0.0071.
