Preparation of Alkali-treaded Fly Ash Adsorbent and Its Application for Cd2+ Removal from Aqueous Solution Beigang Lia, Liyuan Zhaob and Chen Wangc Chemistry ＆ Environment Science College, Inner Mongolia Normal University, Hohhot 010022, Peoples R China alibg@imnu.edu.cn, bzhaoliyuan_1985@126.com, cchensweet0929@qq.com Keywords: Adsorption; Cd2+; Fly ash; Kinetics; Sodium carbonate Abstract.
In this study, we have tried to utilize abundantly and easily available FA as raw material to prepare the large-capacity modified fly ash (MFA) adsorbent by high-temperature calcination, and further to apply it to the removal of Cd2+ from aqueous solution.
Materials and Methods Materials and preparation of the adsorbent The raw fly ash sample used in this work was obtained from the Inner Mongolia Datang International Togtoh power generation limited liability company, China.

Hence, the future work should focus on the incorporation of modelling the rubber materials' behaviour using the Prandtl model under vibration loading, which allows a deeper assessment of the material behaviour and the effect on the damping performance of LRB.

The assumptions in the analysis are: (1) Material is isotropic and ideal elastic-perfectly plastic; (2) Connections of beam and end vertical member are rigid, that of struts, string and other members are hinged; (3) Left boundary condition of BSS is hinge support, and right one is roller support.
The model can consider both material nonlinearities and geometrical nonlinearities and temperature-reduction method is used to simulate prestressing, main nodes of the model are shown in fig. 1.
Conclusion In stage of prestressing initial imperfections decrease the stiffness of BSS so that the deformation of the system slightly increases; but the influence is not obvious, plastic development in section of upper chords is very limited, and most of material of beam is in elastic state so that elastic analysis method can be used in the stage.

The SiO2 colloids were obtained from Huber Engineering Materials (Qingdao) Co., Ltd.
The storage moduli (G′)and loss moduli (G′′) cross as the frequency increases, indicating that the materials are more elastic than viscous at high frequencies.
If G′ has higher magnitude than G′′, it means that the portion of the energy that will be stored in the structure of the material is larger than the portion that will be dissipated by viscous forces.

The cutting force is low while cutting the softened material because of the suitably high cutting temperature.
An increase in the cutting speed results in the higher cutting temperature which leads to the softening work material and easy to cut.
The other reason is that the work material becomes softer and easy to cut due to the higher cutting temperature which leads to a low cutting force ratio at the greater cutting speed as shown in Figure 3.
