(1) preparing silver-loaded spherical activated carbon:
the surface of the spherical active carbon is pre-oxidized by using 2mol/L nitric acid at a constant temperature of 50 ℃ for 120 min. Then, adding spherical activated carbon with an impregnation ratio of 1:3 into silver nitrate solution with a concentration of 0.5mol/L, oscillating for 240min at a constant temperature of 40 ℃, and finally, placing the spherical activated carbon in a tube furnace to reduce for 240min at a high temperature of 460 ℃. Washing the silver-loaded spherical activated carbon by using deionized water until the silver-loaded spherical activated carbon is neutral, and drying the silver-loaded spherical activated carbon.

And adhering the spherical active carbon in a point adhesion mode during carbon application, and thermally setting the composite fabric at 60 ℃ for 60min to obtain the spherical active carbon biochemical protective fabric.
The scanning electron microscope image of the silver-loaded spherical activated carbon is shown in fig. 1b, and as can be seen from fig. 1b, the nano silver particles are uniformly distributed on the surface of the spherical activated carbon, and due to the increase of the concentration of silver nitrate, the phenomenon of particle agglomeration occurs, and the average particle size is 30-40 nm.
Example 3
A preparation method of a spherical activated carbon breathable biochemical protective fabric with strong adsorption performance and antibacterial performance comprises the following steps:
(1) preparing silver-loaded spherical activated carbon:
the surface of the spherical active carbon is pre-oxidized by using 2mol/L nitric acid at a constant temperature of 70 ℃ for 90 min. Then, adding spherical activated carbon with the dipping ratio of 1:4 into silver nitrate solution with the concentration of 1mol/L, oscillating for 300min under the constant temperature condition of 60 ℃, and finally, placing the spherical activated carbon in a tubular furnace to reduce for 120min at the high temperature of 500 ℃. Washing the silver-loaded spherical activated carbon by using deionized water until the silver-loaded spherical activated carbon is neutral, and drying the silver-loaded spherical activated carbon.
(2) Preparing a biochemical protective fabric:
the biochemical composite fabric takes pure polyester woven fabric as base cloth, and is point-bonded by using an epoxy resin adhesive, wherein the number of adhesive points is 100 meshes. And adhering the spherical active carbon in a point adhesion mode during carbon application, and thermally setting the composite fabric for 50min at 70 ℃ to obtain the spherical active carbon biochemical protective fabric. The scanning electron microscope image of the silver-loaded spherical activated carbon is shown in fig. 1c, and from fig. 1c, it can be known that the nano silver particles are uniformly distributed on the surface of the spherical activated carbon, and due to the further increase of the silver nitrate concentration, the phenomenon of particle agglomeration occurs, and the average particle size is increased to 40-50 nm.
The adsorption experiment of the mustard gas simulant, propylsulfide, was performed on the silver-loaded spherical activated carbon prepared in examples 1 to 3. Preparing a certain concentration of propylthioether solution, adding silver-loaded spherical activated carbon with equal mass, oscillating and adsorbing for 12 hours, and measuring the adsorption capacity by using an ultraviolet spectrophotometer. The results of the adsorption experiments are shown in table 1:
table 1 example-3 testing of the adsorption performance of mustard gas simulant, propylsulfide
The result shows that the removal rate of the silver-loaded spherical activated carbon to the mustard gas simulator propylsulfide is up to over 88 percent, which indicates that the silver-loaded spherical activated carbon has good adsorption performance.
The results of the adsorption kinetics experiment performed on the silver-loaded spherical activated carbon of example two are shown in fig. 2 a. As can be seen from fig. 2a, the adsorption process reached an equilibrium state after 12 hours. The data of the fitting results of the quasi-second order adsorption kinetic equation and Langmuir adsorption isotherm model to adsorption are shown in FIGS. 2b and c. From fig. 2b and c, it can be seen that the fitting degree of the adsorption process with the quasi-second order kinetics and Langmuir adsorption isotherm model is high, which indicates that the surface energy of the silver-loaded spherical activated carbon is uniformly distributed and is a monomolecular layer adsorbent, and indicates that the adsorption of the silver-loaded spherical activated carbon to the mustard gas simulator propylsulfide is a chemical adsorption process. The chemical adsorption has stronger binding force by forming new chemical bonds for adsorption, which shows that the existence of the nano silver enables the spherical active carbon to have stronger adsorption effect.
Selecting escherichia coli as a strain, and referring to part 3 of evaluation of antibacterial performance of GB/T20944.3-2008 textiles: the results of the tests on the antibacterial performance of the spherical activated carbon breathable biochemical protective fabrics prepared in examples 1 to 3 by the oscillation method are shown in table 2:
table 2 test of antibacterial property of biochemical protective fabric prepared in examples 1 to 3
The result shows that the bacteriostatic rate of the spherical activated carbon biochemical protective fabric is up to more than 99%, which indicates that the spherical activated carbon biochemical protective fabric has excellent antibacterial performance.
The permeability of the activated carbon permeable biochemical protective fabric prepared in examples 1-3 was measured by a yg (b)461E digital fabric permeability tester, and the results are shown in table 3:
table 3 test of air permeability of biochemical protective fabric prepared in examples 1 to 3
The result shows that the air permeability of the spherical activated carbon biochemical protective fabric is as high as more than 2000mm/s, which indicates that the spherical activated carbon biochemical protective fabric has excellent air permeability. The fabric prepared by the method has good wearing comfort.
