| Abstract: | Potassium oxide and sodium oxide(K2O,Na2O) in fly ash were determined by flame atomic absorption spectrometry(FAAS).In the analytical procedure,the sample was dissolved in a mixed acid composed of HF and HClO4,other elements could be eliminated by SrCl2.This method has the advantages of easily operation,good reproductivity and high sensitivity.This method can be used for the determination of K2O,Na2O in fly ash. |
