Abstract

A reference material of Coffea arabica leaves from a farm with organic management certification was developed at CENA/USP. Neutron activation analysis was used to determine chemical elements, including assessment of homogeneity and stability. The material was characterized for Ba, Br, Ca, Co, Fe, K, La, Na, Rb, Sc, Sm, Sr and Zn. Reference values were assigned to all elements except Co and Zn whose homogeneous distribution in the material could not be confirmed.

中子活化分析用于开发有机咖啡叶参考材料

CENA/USP 开发了一种来自获得有机管理认证的农场的阿拉伯咖啡树叶参考材料。中子活化分析用于确定化学元素，包括评估均匀性和稳定性。对材料中的 Ba、Br、Ca、Co、Fe、K、La、Na、Rb、Sc、Sm、Sr 和 Zn 进行了鉴定。除了钴和锌无法确认在材料中的均匀分布外，其他元素都有参考值。
