Separation and accurate determination of iron and aluminium in a single sample of silicate rock.
A procedure for the separation and subsequent determination of iron and aluminium in silicate samples is given. The anion-exchange separation of iron(III) from vanadium was studied under the conditions of rock analysis. The salt content of the sample solution and the applicability of resins were studied to determine the optimum conditions for the separation of iron and aluminium. The proposed procedure was tested by determining iron and aluminium in the Geological Standards S1 and W1.
