| Abstract: | The polyether polyol specimen was dissolved in the ethyl alcohol-water mixed solvent, and then the content of potassium ion and sodium ion in the polyether polyol was determinated directly by atomic absorption spectrophotometer. This method was suitable for defermination of potassium ion and sodium ion in polyether polyol more than 0.5×10~(-4)％, and the procedure is simpler, the time is short, suitable for analysis in situ. |
