Avaliação da mineralização de arroz em sistema de refluxo para a determinação de Cu, Fe, Mn e Zn por FAAS

This paper describes the evaluation of a new method of sample preparation using a cold finger system with continuous water flow for rice analysis by flame atomic absorption spectrometry. The limits of detection for Cu, Fe, Mn and Zn for the proposed method were 0.36, 1.84, 2.12 and 0.16 mg kg-1, res...
