  • Title: Determination of manganese in urine and whole blood samples by electrothermal atomic absorption spectrometry: comparison of chemical modifiers.
    Author: Pinto FG, Rey UV, Fernandes EF, Silveira JN, Amorim L, da Silva JB.
    Journal: Anal Sci; 2006 Dec; 22(12):1605-9. PubMed ID: 17159325.
    Abstract:
    In this work, methodologies to determine manganese (Mn) in urine and whole blood by electrothermal atomic absorption spectrometry were developed. The use of Ru, Rh, and Zr as permanent modifiers, Pd as a modifier in solution, and the condition without modifier were investigated for the direct determination of Mn in urine and whole blood samples. The best results for Mn in urine and in whole blood were obtained without modifier use. The analytical characteristic, such as accuracy, precision and limit of detection of the proposed methodology were adequate.
