摘要
研究表明稻草改性后吸附铜离子的能力得到很大提高。研究表明吸附相当好地符合假二级吸附速率模型,测定了在4个温度下(15℃,27℃,37℃,50℃)的吸附速率常数。吸附平衡可用Langmiur吸附模型和Freundlich吸附模型处理。讨论了pH对吸附的影响。
Adsorption of Cu (II) by modified rice straw was studied, and results indicated that the model was well in accordance with the second order kinetic model. The equilibrium nature of copper (II) adsorption at different temperature was described by Langmuir isotherm and Freundlich isotherm, and the effect of pH on adsorption of copper ion was also discussed.
