The determination of manganese by electrothermal atomic absorption spectrometry with a graphite furnace at constant temperature

摘要: Abstract Many of the interferences reported earlier for determination manganese in a graphite furnace were not found when modern was used. At high levels chloride matrix, an interference which observed reduced determined under constant temperature conditions. In this work, sample introduced on tungsten wire after had reached constant, preset temperature. Drying and ashing accomplished outside atomization furnace, reducing contamination from matrix materials.
