| Abstract: | Magnesium oxide （MgO） in fly ash was determined by flame atomic absorption spectrometry（FAAS）.The sample was dissolved in a mixed acid composed of HF and HClO4,and other elements could be eliminated by SrCl2.This method is characterized with easily operation,good reproductivity and high sensitivity.Also it represents a good linear relationship with MgO of 0.10—2.00μg/mL.The detection limit is 0.02%.This method can be used to the determination of MgO in fly ash. |
