Carbonaceous materials for the production of aluminium. Petroleum coke. Determination of trace metals by inductively coupled plasma atomic emission spectrometry1 Scope This International Standard applies to carbonaceous materials for the production of aluminium. This International Standard describes a test method which covers the analysis for commonly determined trace metals in test specimens of raw and calcined petroleum coke by inductively coupled plasma atomic emission spectroscopy. It can also be applied to other heat treated carbonaceous materials e. g. coal tar pitch coke, anthracite. Elements to which
