摘要：The depression of the analytical signal of calcium by phosphate ion when using turbulent (H2/02 and H2/A/entrained air) and laminar (C2/H2/air) flames in
flame spectro-ietry is studied. Measurements of flame emission of calcium as a

concentrations. The cau of the interference is probably a result of either slow
