Abstract
Overview
ISO 8658:1997 specifies a laboratory method for the determination of trace elements in green and calcined coke intended for aluminium production. The method uses sample ashing, fusion, dissolution and measurement by flame atomic absorption spectrometry (FAAS). It is written for coke with ash ≤ 1% (m/m) and defines procedural steps, required reagents and apparatus to obtain reliable trace-element results relevant to aluminium smelting feedstocks.
