| Resumo: |
Three botanical substrates and one milkpowder were mineralised and digested by the following methods in order to measure their total mercury content: (1) HF/HNO<sub>3</sub>-KMnO<sub>4</sub>; (2) H<sub>2</sub>SO<sub>4</sub>/HNO<sub>3</sub>-KMnO<sub>4</sub>; (3) H<sub>2</sub>SO<sub>4</sub>/HNO<sub>3</sub>- H<sub>2</sub>O<sub>2</sub>; (4) H<sub>2</sub>SO<sub>4</sub>/HNO<sub>3</sub>-UV irradiation/KMnO<sub>4</sub>; (5) H<sub>2</sub>SO<sub>4</sub>/HNO<sub>3</sub>/V<sub>2</sub>O<sub>5</sub>-catalyst KMnO<sub>4</sub> and (6) H<sub>2</sub>SO<sub>4</sub>/HNO<sub>3</sub>/V<sub>2</sub>O<sub>5</sub>-catalyst H<sub>2</sub>O<sub>2</sub>. Of these methods (1) and (5) yield similar results and produce relative standard deviation values between 0.8 and 7.6. Method (5) is the faster of the two. No interferences with the detection of Hg were observed.
