Analytical Chemistry of Aluminium

The preparation described in the reference is based on the reaction between the metal and HBF4 in presence of hydrogen peroxide. The two former reactants are not usually available. 

Aluminium can be determined by atomic absorption, the conditions being similar to those used for B except that the wavelength of measurement is 309.3 nm and that the optimum concentration is 0.1 0.3 of the range used for B.
