Abstract

Gas adsorptive properties of dust, which is exhausted from cupola, have been investigated at room temperature. The cupola dust adsorbed some gases, and in particular hydrogen sulfide (H₂S). The adsorptive mechanism for H₂S has been examined through the characterization of the dust by X-ray fluorescence analysis, X-ray diffraction, transmission electron microscopy, measurement of adsorptive capacity, etc. Consequently, it was found that the property was induced by the spinel nanocrystals with 10-50 nm in dimension such as (Mn_xZn_1-x)(Mn_yFe_1-y)₂O₄ solid solutions in the dust. Furthermore, the characterization revealed that the adsorptive capacity of the dust for H₂S was promoted by the NaOH treatment. In addition, it was found that the Mn content of the dust correlates with the adsorptive capacity for H₂S.
