dc.description.abstract<正> 关于铀、钍的分离与测定方法国内外已有不少报道,但分离流程一般都比较冗繁,且回收率低,对海洋样品尤其如此。本文在已建立的离子交换分离铀、钍流程的基础上,采用柱柱法进行海洋样品中铀、钍的分离并用α能谱法测定铀、钍的同位素含 【英文摘要】 A simplified method has been developed to separate and estimate the activities of uranium and thorium isotopes in oceanic samples. Uranium and thorium can be simultaneously separated from the sample through an anion exchange column in NH4NO3-HNO3 medium and separately estimated by means of alpha spectrometry. Seven samples including sea water, sediments, manganese nodule, coral and fresh oyster, were collected and practised with this method, It was demonstrated that the procedure is simple, efficient, and c...zh_CN
