Petroleum products - Determination of aluminium and silicon in fuel oils - Inductively coupled plasma emission and atomic absorption spectroscopy methods
The principle of the method specified is heating a weighed quantity of homogenized sample in a clean platinum basin, removing the combustible material by burning, finally removing the carbon by heating, fusing the residue with a dilithium tetraborate/lithium fluoride flux, digesting the fused mixture in a solution of tartaric acid and hydrochloric acid, dilution to volume with water, measuring the solution by ICPES or AAS. The method is applicable for concentrations between 5 mg/kg and 150 mg/kg for aluminium and 10 mg/kg and 250 mg/kg for silicon.
