Summary
A new sensitive and selective method for determining aluminium with Chrome Fast Pure Blue B and cetyltrimethylammoniumbromide is described. Lambert-Beer's law is strictly obeyed between 0.0102 and 0.0816μg/ml in the final dilution. The maximum absorbance is shown at 645 nm. The molar absorbance is 1.23×105 l mol−1 cm−1. 44 ions have been studied concerning their interference. The determination of aluminium in steels, soil and ashes of plants is described.
