生物材料的质子活化分析

Proton Activation Analysis of Biological Material

本工作利用14.2Mcv质子活化分析法测定了生物材料中的多个元素。建立了用Y作内标、石墨粉作基体物的内标法,能对生物样品中的Ca、Ti、Vi、Cr、Fe、Ni、Cu、Zn、Ge、Se、Sr、Cd、La和Pb等元素进行测定。方法灵敏度达到2×10^(-5)～5×10^(-8)g/g。

Bioligical materials have been investigated by 14.2 MeV proton activation ana-lysis using internal standard method, Concentrations of elements Ca, Ti, V, Cr, Fe, Ni, Cu, Zn, Ge, Se, Sr, Cd, La and Pb in these samples have been determined in the range of 5×10^(-8)～2×10^(-5)g/g.
