Because of the particular crystal structure of montmorillonite, montmorillonite gel has many applications, and can be widely used in daily chemical industries such as dentifrice and cosmestics [1,2], pharmaceuticals [3,4] and other industries.
Because of it’s special character of charges and asymmetric structure, montmorillonite can restrain the virus,bugs and toxin in the alimentary canal, protect the alimentary canal mucous membrane.

ARS is a mature analytic method on geophysics, physics, material science and analytical chemistry for parameter analysis of sample, whose shape and size are strictly limited [2-4].
Theoretical Background ARS is the study of the mechanical resonance structure of objects, which are composed of elastic materials that have natural modes of vibration.
The natural frequencies are global properties of a given structure and the presence of structural differences causes shifts in these resonances.
Sample preparation As previously mentioned, the data about the object’s physical structure and composition are acquired by ARS, from which some meaningful information can be extracted, it can be used to uniquely identify a particular class of Hazards material.

During the practical testing process, it is found that different solution media and different electrode structure will cause distinct reduction curve especially when the excitation source is not constant potentiometer.

It is observed that the nanocomposites prepared by electroforming without ultrasonic and the cathode keep static (Fig. 5a) shows a rather non-uniform structure, and the crystal grain is rough and with non-uniform distribution.
The nanocomposites prepared by electroforming by rotating cathode in ultrasonic field (Fig. 5d) exhibits a denser structure and finer grains.
On the other hand, the ultrasonic and the rotating cathode can strengthen the dispersion strengthening effect of CeO2 nanoparticles, urge grain of the nanocomposites, Interrupted normal growth process of Ni crystal, refined the grain, changed the way of the crystallization of the matrix metal Ni, all that enchanced the nanocomposites refining, metal structure compact and uniform, and present a higher microhardness[12].

Due to HA structure, high molecular weight value, and strong intramolecular interactions, it could be suitable base for hydrogel preparation.
FTIR spectra indicated interaction between EPL and HA and successful formation of cross-linked hydrogel structure via amide bond linkage.
However, SEM micrographs of both hydrogels show well-organized, homogenous, and porous structure (20–200 µm) with interconnected porosity.
