摘要： 研究了药用活性炭对硫酸奎宁吸附性能的影响，并采用Langmuir和Freundlich吸附等温线模型拟合了活性炭对硫酸奎宁的吸附行为。结果表明：硫酸奎宁吸附量随药用活性炭用量的增加呈上升趋势，但吸附效率却呈下降趋势。在所研究的条件下，活性炭对硫酸奎宁的吸附量随温度和初始浓度的升高而增大，在313 K吸附值最大为123.457 mg·g-1。与Freundlich吸附模型（r2f<0 r2l="">0.97），说明Langmuir模型适用于所研究的体系。

Abstract: In this study, the adsorption effect of medicinal activated carbon for quinine sulfate(QS) removal from aqueous solutions was investigated. The adsorption behavior of QS onto medicinal activated carbon was fitted with Langmuir and Freundlich adsorption isotherm models. The results showed that an increase the dosage of activated carbon enhanced the adsorption capacity, but failed to increase the QS removal efficiency. In the studied conditions, the adsorption of QS onto activated carbon rised with increasing temperature and the initial QS concentration, and the calculated maximum adsorption capacity of activated carbon was 123.457 mg·g-1 at 313 K. Compared with Freundlich model (r2f<0 the="" experimental="" data="" indicated="" that="" adsorption="" isotherms="" were="" fitted="" well="" with="" langmuir="" equilibrium="" isotherm="" r2l="">0.97).
Key words: medicinal activated carbon; adsorption capacity; quinine sulfate
