| Abstract: |
A modified peat was prepared by using nitrate and natural peat from Yiyang city in Hunan Province. The adsorption properties of the nitrifying peat for Methylene blue was investigated in aqueous solution. The effect of the adsorbent dosage, time and the initial concentration of methylene blue on the adsorption capability was discussed. The result showed that time and the adsorbent dosage had greater influence on the adsorption of Methylene blue, the adsorption of Methylene blue by Nitrifying peat was a rapid process, and in 20 min in the adsorption rate reached more and 60%, the adsorption amount was approximately proportional to the initial concentration( 20-100 mg /L). Langmuir and Freundlich isotherms were used to fit the equilibrium data, and it was found that the adsorption isotherm followed the Langmuir model. |
