From SEM analysis, in the embodiment of the present embodiment, the nanoscale montmorillonite and the alginate form an outer layer, the diatomite is a middle layer, the graphene oxide is in an inner layer region, two kinds of particles are basically formed in comparative example 1, one is the alginate component coated montmorillonite, the other is the alginate component coated diatomite, there is basically no three-layer core-shell structure, the two layers of core-shell structures are formed in comparative example 2, the outer layer is the graphene oxide, the montmorillonite and the alginate component, and the inner layer is the diatomite, from the aspect of performance detection, the adsorption capacity of the adsorption particles of the three-layer core-shell structure formed in the embodiment is substantially higher than that of the particles of the configuration in comparative example 1-2, and the adsorption performance of the alloy material formed in the embodiment can be substantially improved by adding a small amount of the three-layer core-shell adsorption particles.
The above is only a preferred embodiment of the present application, and the protection scope of the present application is not limited to the above examples, and all technical solutions belonging to the concept of the present application belong to the protection scope of the present application. It should be noted that modifications and adaptations to the present application may occur to one skilled in the art without departing from the principles of the present application and are intended to be within the scope of the present application.
