摘要
利用油茶果壳活性炭填料柱对水中铜离子进行动态吸附。探讨了pH值、初始质量浓度、床层高度等因素对穿透曲线的影响。结果表明,油茶果壳活性炭能有效去除水中的铜离子,随着床层高度的增高、pH的增大和初始浓度的减小,油茶果壳活性炭填料柱对水中铜离子的吸附穿透曲线位点向右移。通过数学模型得到的速率常数、相关系数、平衡吸附量和动力学参数,能较好地描述油茶果壳活性炭填料柱吸附铜离子的吸附动力学。
Dynamic adsorption of Cu2＋ from aqueoous solution by activated carbons prepared from oiltea shell was investigated in a fixed-bed column.The effects of important parameters on breakthrough curve,such as the filler height,concentrations and the initial mass concentration of Cu2＋,were studied.The results showed that activated carbons prepared from oiltea shell had a good absorption on Cu2＋.As the filler height,with increasing pH and concentration,the breakthrough point in the breakthrough curves moved to the right.The rate constants,correlation coefficients,equilibrium adsorption capacity and kinetic parameters,which were calculated through mathematical models,can be used to describe the adsorption kinetics of Cu2＋ by activated carbons prepared from oiltea shell well.
