摘要 研究了安吉蒙脱石对抗菌金属离子Ag+ 、Zn2 + 及Cu2 + 的吸附反应容量 ,发现安吉蒙脱石对抗菌金属离子的吸附等温线可用Freundlich方程加以拟合。抗菌金属离子按照其吸附容量大小的排列次序为Cu2 + >Zn2 + >Ag+ ,此次序由三种离子的水化热、离子半径及价态所决定。 The adsorption capacity of Anji montmorillonite for antibacterial metal ions,including Ag +?Zn 2+ and Cu 2+ ,was studied in this work. The adsorption isotherm of the antibacterial metal ions could be fitted well by Freundlich equation. The adsorption capacities for different antibacterial metal ions followed an order of Cu 2+ >Zn 2+ >Ag +, Which was decided by the hydration enthalpies,the ion radii and the valency of the ions.
