摘　　要：研究了蛭石对稀土离子的吸附作用 ,结果表明 :蛭石具有较强的吸附性能 ,吸附速度较快 ,影响吸附的主要因素是 pH值 ,其吸附机理符合阳离子交换吸附形式 ;通对稀土原地浸矿尾液的处理 ,达到回收稀土的目的 。With vermiculite as adsorbent, its adsorption property to RE + was investigated。 The result was shown vermiculite had stronger adsorption property to RE + and more fast adsorption speed。The study illustrated pH was a key factor to adsorption affect, and the mechanism of adsorption was cation exchange。It was managed that rare earth could be reclaimed by treating rare earth raw material with vermiculite, moreover, the method can be applied to the reclamation of rare earth with low concentration in production
