Adsorption of Acid Red G Dye from Solutions by Raw Bentonite and Bentonite- Cationic Starch Composite Hualing He1,a, Zhicai Yu1,b, Peng Liang1,c 1Colleage of Chemical Engineering and Material Science, Eastern Liaoning University, 325 Wenhua Road, Dandong, Liaoning, 118003, China aEmail: hehualinghe@126.com, bemail:yuzhicaicai@163.com, cemail:liangpenglong@163.com Keywords: Adsorption, RB/CS composite, Raw bentonite, Kinetics, Equilibrium Abstract.The adsorption of acid red G dye onto raw bentonite/cationic starch(RB/CS) and raw bentonite (RB) was investigated in aqueous solution in a bath system with respect to the adsorption kinetics and adsorption isotherms, respectively.
In summary, the results showed that RB/CS could be employed as low-cost materials for the removal of acid red G dye from effluents compared to RB.
Experimental Materials The raw bentonite (RB) used in this study was obtained from Sangong Chemical industry Co.Ltd.

In this study, corrosion property of both weld metal and base metal was investigated with some electrochemical methods in natural sea water solution, in case of being welded with some welding methods and welding materials to the exhaust valve specimen as the base metal.
In this study when repair welding with various welding methods and welding materials like foreign and domestic electrode was performed at the exhaust valve part as the base metal, corrosion property of both base and weld metal were investigated with some electrochemical methods such as corrosion potential, polarization curves, cyclic voltammogram etc.. 2.
Experimental procedure Ni-Cr steel(KS:STR-3) was used with base metal(BM) and stellite electrode was also used for repair welding materials with foreign and domestic electrode respectively.
Conclusions When repair weld was performed at the exhaust valve with some parameters such as welding methods, welding materials, corrosion resistance between base metal and weld metals was investigated with electrochemical view point.
Corrosion resistance of weld metal irrespective of welding methods and welding materials was clearly superior to the base metal.

Recent advances in porous materials, including carbon materials[1-3], zeolite[4,5], metal-organic frameworks (MOFs)[6-8], and covalent organic frameworks (COFs)[9,10], have provided an effective solution to the problems.
Thus many effects have been made to improve the surface properties of the carbon materials.
