中文摘要：

对Li／Mn为0．7的离子筛分别进行了铜钴镍的掺杂，XRD检测和化学分析表明掺杂元素进入了离子筛的晶格；掺入铜钴镍后离子筛中锰的溶损率分别降低了2％、1．3％、1．2％；饱和吸附容量随掺入元素量的增加逐渐变小，当掺入铜钴镍的量由0增加到0．15时，饱和吸附容量由27．6mg／g分别下降到7．8mg／g、13．3mg／g、18．3mg／g。铜钴镍在离子筛中能降低锰的溶损率，但同时也降低了饱和吸附容量。

英文摘要：

The doped ion sieve （Li/Mn=0.7） with Cu, Co and Ni is characterized by XRD and chemical analysis. The result shows that the three elements Cu, Co and Ni enter into the crystal lattice of ion sieve, which leads to the percentages of loss manganese decrease by 2%, 1.3%, 1.2% respectively. With the increasing of doped element, saturation adsorption capacity of ion sieve decreases gradually. When the quantity of copper, nickel and cobalt increases from 0 to 0. 15, the saturation adsorption capacity drops from 27.6 mg/g to 7.8 mg/g, 13.3 mg/g and 18.3 mg/g respectively. The nickel, cobalt and copper in ion sieve can reduce dissolved manganese, but it also reduces the saturated adsorption capacity of ion sieve.
