The goal of this work is to study the possibilities for quantitative determination of the number of iron atoms in the mineral core of ferritin by atomic absorption spectroscopy (AAS). Distinctive AAS measurements show iron content between 1000 and 4500 atoms per molecule ferritin.[1-61, 2, 3, 4, 5, 6] This motivated us to investigate the amount of iron in the horse spleen ferritin with atomic absorption spectroscopy under application of the Bulgarian standard BDS EN 14082/2003 FoodstuffsDetermination of Trace ElementsDetermination of Lead, Cadmium, Zinc, Copper, Iron and Chromium by Atomic Absorption Spectrometry (AAS) after Dry Ashing.[7] We have obtained as a result 1792 atoms in one ferritin molecule. This result is in accordance with previous results, published by leading researchers.[4,5] The investigation of the iron content with AAS under the use of the Bulgarian standard can be a good opportunity to study many other objects of biological interest.
