摘　　要：Cl—5208萃淋树脂是中性膦类树脂,具有对铀、钍吸附容量大,水溶性少,流速快等优点。本文研究了用Cl—5208树脂吸附分离铀,钍及其他元素的条件,拟定了采用铂坩埚偏硼酸锂熔矿,ICP—AES和AAS法测定方钍石、晶质铀矿中的钍、铀、铅、铁、铝、钙、镁、钛、锰、钾。Cl-5208 resin was used successfully for the separation of U and Th from Pb,Fe,Al,Ca,Mg,Ti,Mn,K,Na and Si in 3 mol L^(-1)HNO_(3).The sample(5mg)was fused with lithium metaborate and dissolved 3 mol L^(-1)HNO_(3).The sample solution was passed through a column containing Cl-5208 resin,U and Th were absorbed and separated from other elements.The determinations are completed by ICP-AES and AAS.The recoveries of the above 12 elements were 96.25-104%.
