Forms of metals in fly ash and flue gas desulphurization products and methods to determine these forms; Metallien esiintymismuodot lentotuhkassa ja rikinpoistotuotteissa

Abstract

The aim of this literature study was to find out possible forms of metals in fly ash and flue gas desulphurization products, and experimental methods to study these forms. The information about the forms of metals is needed, for example, in modelling of dissolution and environmental effects of wastes. Literature provides much information about minerals in the fly ash. The exact mineral composition of ash, however, is influenced by, e.g., the plant-specific combustion conditions. Even if the mineral composition of the main elements is constant, the mineral composition of the trace elements may vary a lot. In the literature there is little information about the minerals in flue gas desulphurization products. In this literature study the sequential extraction method is discussed in more detail, because the results obtained by this technique can be used to interpret the behaviour of metals in nature. Experimental results can be utilized in chemical modelling. If experimental results are compared with the results obtained by modelling, information about the phases which control the solubility can be received. Information about whether the phase is going to dissolve or precipitate can also be received. Experimental leaching and extraction data can be used in modelling, and the solubility  More>>
