Abstract

Instrumental neutron activation analysis was performed to determine Na, Mg, Al, Cl, Sc, V, Cr, Mn, Fe, Co, Ni, Rb, Sb, Cs, Ba, Ce and Eu in the Pacific core sediment. Selenium was also determined by neutron activation analysis, by applying a solvent extraction method with 2,3-diaminonaphthalene (DAN) as a post-irradiation procedure, after the wet-ashing of the sediment. Homogeneity of trace constituents in the sediment and neutron flux corrections for accurate determination were also investigated.

摘要

采用仪器中子活化分析法测定了太平洋岩芯沉积物中的钠、镁、铝、氯、钪、钒、铬、锰、铁、钴、镍、铷、锑、铯、钡、铈和铕。沉积物经湿灰化后，还采用以2,3 -二氨基萘（DAN）为溶剂萃取剂的中子活化分析法测定了硒，作为辐照后程序。同时还研究了沉积物中痕量成分的均匀性以及为准确测定而进行的中子通量校正。
