Adsorption of Methyl Orange on Guanidine Modified Attapulgite
Abstract:
The adsorption capability of 16 alkyl-guanidine modified attapulgite for methyl orange was studied.The effects of adsorption time,the amount of adsorbent,and the concentration of the dyes were also studied.The results showed that the adsorption capacity of the modified attapulgite clay was improved obviously,and the decolorization rate of methyl orange simulated wastewater dyes was higher than 98%.The relationship between adsorpting capacity(qe) and equilibrum mass concentration(ρe) was in accordance with the isothermal adsorption Langmuir equations.The adsorption heat is less than 40 kJ/mol.The adsorption exhibits a physical adsorption.
