dc.description.abstractAsphaltites derive from petroleum origin. The combustion of asphaltites produces fly and bottom ashes that are characterized by a high content of valuable elements such as vanadium, nickel, molybdenum, uranium, thorium, sulfur and unburnt carbon [1]. This study presents the concentration and speciation of nickel in bottom ash of Milli (Sirnak), SE Anatolia in Turkey. Determination of total nickel in asphaltite bottom ash was performed in two stage microwave-acid digestion followed by inductively coupled plasma optical emission spectrometer (ICP-OES). The revised BCR (Commission of the European Communities Bureau of Reference) scheme applied is a four-step sequential extraction procedure. That was proposed to harmonize and validate the methods used in fractionation studies in soils. A four step sequential extraction process to speciation of nickel from asphaltite bottom ash was investigated [2]. Relative abundances of the remaining fractions follow the order: residual >Organic matter and sulfides> exchangeable with water and acid> Iron and manganese oxides soluble. Nickel speciation scheme allows quantitative knowledge of nickel distribution in asphaltite bottom ash and their toxicity, mobility, leachability, bioaccumulation and bioavailability. © SGEM2017.
