Application of Classical Titration and ICP-OES Techniques for the Determination of Total Iron, Metallic Iron, and Iron (II) as Tools for Assessing the Feasibility of Ferrous Metallurgical Waste Management

The introduction of ferrous waste into a technological process requires knowledge of the quantitative fraction of iron at various oxidation levels. The research work discussed in the article aimed to develop an effective strategy for handling the test material in order to obtain information concerning iron speciation, relevant for assessing the reuse potential of ferrous waste. The determination of various forms of iron in metallurgical waste involved the use of titration methods and the ICP-OES technique. The iron content in the waste material ranged from a few to more than 90 %, whereas the proportions of individual forms varied. The test results confirmed the effectiveness of the ICP-OES technique
