Abstract
The hydrogen sulfide sorptive property of founding dust exhausted from a cupola furnace was investigated at room temperature by X-ray diffraction, transmission electron microscopy, measurement of adsorptive capacity, etc. Consequently, it was found that this property was induced by the spinel-type nanocrystals composed of transition elements in the dust. Furthermore, characterization revealed that the H2S sorptive capacity of the dust was enhanced by NaOH treatments to extract the spinel-type nanocrystals from amorphous SiO2 matrix. In addition, it was found that the H2S sorptive capacity was correlated with Mn content in the spinel-type nanocrystals.
