Coal bottom ash (CBA) contains many elements that exist in different forms, which may change throughout the coal combustion process. This study presents the concentration and speciation of zinc in bottom ash of coal. Determination of total zinc was performed by two-stage microwave-acid digestion followed by ICP-OES. A sequential extraction process to speciation of zinc from coal bottom ash was investigated [1]. The definition of species is based on several different levels of atomic and molecular structure where c...
