Aluminium metal was dissolved with hydrochloric acid, and after the solution was atomized, the intensity of the flame emission of sodium at 589 mμ was measured using Beckmann model DU spectrophotometer and its flame attachment. The gas pressures suitable for the flame photometry of sodium was first investigated and the influencies of acids and aluminium were also studied. By applying this method, 0.001〜0.01 per cent of sodium in aluminium metal could be rapidly determined without seperation of aluminium.
