Scope

This Standard specifies the atomic absorption spectrometric method for the
determination of nickel content in nickel ores, in which an acidic solution is prepared
after acid dissolution or alkali fusion separation.
This Standard applies to the determination of nickel in nickel ores.
The measuring range: 0.1% ~ 6.0% of nickel.
