TL;DRAbstract

Different strategies for sample preparation, the optimization of instrumental parameters and the evaluation of different chemical modifiers for the determination of cadmium, copper and manganese in honey by graphite furnace atomic absorption spectrometry were developed. Honey is a heterogeneous matrix, which has great commercial and environmental importance. However, few studies concerning its mineral content have been carried out in Brazil.
