Adsorption of Basic Dye in Aqueous Solution by Mesoporous Carbon Materials Xiaoping DONGa, Jie FUb, Junhao JINc and Chen CHENd Department of Chemistry, School of Sciences, Zhejiang Sci-Tech University, Hangzhou 310018, China axpdong@zstu.edu.cn Keywords: Dye adsorption; Malachite green; Mesoporous carbon; CMK-3 Abstract.
Mesoporous carbon CMK-3 with high surface area and opened pore structure was used to adsorb the basic dye, Malachite green (MG).
The excellent adsorption capability of activated carbon compared with other non-carbonaceous materials is due to the porous structure and high surface area.
In this work, we studied the adsorption behavior of a typically basic dye, malachite green (MG, C.I. 4000), on a mesoporous carbon CMK-3, which possesses high specific surface area, 3~4 nm pore size and opened porous structure.
The ordered structure, an exactly negative replica of mesoporous silica SBA-15 with a hexagonal arrangement of cylindrical mesoporous tubes, can be observed in CMK-3 sample.

The STO at temperatures above 105K [5] presents itself in the form of cubic perovskite structure (ABO3) with a space group pm3m, lattice parameter about 0.3905nm at room temperature and melting point at 2.353K [6].
Experimental Procedure Solid State Reaction (SSR) The precursors SrCO3 (97%-Vetec Chemistry), TiO2 (99.8%-Vetec Chemistry), La2O3 (99.9%-Sigma-Aldrich) and Nd2O3, (99.9%-Sigma-Aldrich) were mixed in stoichiometric proportions to form SrTiO3 (STO), Sr0.96La0.04TiO3 (STO-04La), Sr0.96Nd0.04TiO3 (STO-04Nd) and Sr0.96La0.02Nd0.02TiO3 (STO-02La02Nd).
Precipitation powder (PP) The precursors SrCO3 (97%-Vetec Chemistry), Ti(C4H9O)4 (97%-Sigma-Aldrich), La2O3 (99.9%-Sigma-Aldrich) and Nd2O3 (99.9%-Sigma-Aldrich) were dissolved in aqueous solution of HNO3 (6 M) in stoichiometric ratio in order to obtain STO, STO-04La, STO-04Nd and STO-02La02Nd.
It can be observed that at constant temperature, the STO cubic perovskite structure lattice parameter changes linearly, according to the molar concentration and cation size of the constituents, which is in agreement to the empirical Vergard's law [25,26].

So, it is necessary to study the influence of crystal structure, surface properties on flotation behavior[3, 4].
The most important aspect is the hydrophobic ability which insure the flotation process is judged by the structure and size of nonpolar group [10].
The solution chemistry analysis and infrared spectrogram of kaolinite and DN12-kaolinite show that the main mechanism of absorption is electrostatic interaction.

Amide surfactants have modified structures with lipophilic groups connecting hydrophilic groups through amido bond.
Surfactants are widely used in many industries like food, chemistry, drug, paper manufacturing, leather and fur making, materials, environmental protection and textiles as important functional fine chemicals to improve process, efficiency, product quality, and to save energy because of their unique chemical nature at interfaces.
N-acyl amino acids surfactants are a type of amide surfactants made from modifying the structure of soap.
In order to obtain better properties of the cationic surfactants, new structure of the quaternary ammonium salts containing amide groups were synthesized by the use of dimethyl carbonate.

The subsequent surface treatment via atmospheric pressure plasma jet or vacuum blasting allowed the modification of the microscopic roughness as well as the surface chemistry.
If surfaces were free of contaminations, no differences between microscopically smooth and slightly structured surfaces were found.
After analysing the surface roughness and chemistry, quasi-static and fatigue tests were carried out on single lap shear joints.
Fig. 1 shows the surface roughness, where a smooth respectively uneven structured surface was formed in case of A50001 and A50002 and an oriented surface structure in case of peel ply 408.07P and 08940.
In addition, the stress peaks caused by the structuring of the boundary layer trigger the failure within the adherent.
