竹炭对亚甲基蓝的吸附平衡和动力学研究
Adsorption equilibrium and kinetic of methylene blue on bamboo carbon
摘要
Abstract
The adsorption equilibrium and kinetic of methylene blue dye on bambo carbon(BC) were examined at room temperature, and the effect of the original concentration of methylene blue and the amount of bamboo carbon were measured. Adsorption isotherm of the methylene blue (MB) on the bamboo carbon was determined and correlated with Langmuir and Freundlich adsorption isotherm equations. Two simplified kinetic models including pseudo-first-order and pseudo-second-order equation were selected to follow the adsorption processes. The result shows that the equilibrium data for methylene blue adsorption fit to the Freundlich equation(R2 =0. 99) well. The adsorption of methylene blue could be best described by the pseudo-second-order equation. The kinetic parameters of this best-fit model were calculated and discussed.关键词
