补充资料:吸附共沉淀
分子式:
CAS号:

性质:在含有放射性核素的溶液中形成表面发达的常量物质的离子晶体(或无定形沉淀)时,放射性核素虽不能与常量物质形成共结晶,但却能被吸附在晶体表面,随常量物质晶体(或无定形沉淀)一起被载带沉淀出来,这种现象就称作吸附共沉淀。离子晶体(或无定形沉淀)吸附放射性核素有如下经验规律:(1)当放射性核素离子与常量物质晶体中持相反电荷的离子形成难溶的或难解离的化合物时,放射性核素易被吸附于晶体表面;(2)放射性核素所带的电荷与晶体表面所带的电荷相反时,则吸附量大,实验条件影响晶体表面电荷情况和吸附作用;(3)放射性核素被吸附的量与晶体表面积的大小呈正相关关系。
