Neutron activation analysis for development of organic coffee leaves reference material
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.
