Concentrations of the elements Br, Ca, Co, Cr, Fe, K, La, Na, Sc and Zn were determined. Comparisons were made between the results obtained with published data for aspirins from foreign countries. Certified reference materials, INCT-MPH-2 Mixed Polish Herbs were analyzed for quality control of the analytical results.299-301openAccessacetylsalicylic acidelementstrace amountsimpuritiesneutron activation analysisArtigo de periódico228010.1007/s10967-009-0515-7
