| Abstract: | A study on the flame spectrophotometry determination of K+ and Na- in polyether polyol is reported in this paper. Polyether polyol samples are dissolved directly by alcoholwater.The standard polyether polyol without K- and Na- is used in background correction.The method proposed has the advantages of sample treatmenting simple,rapid and accurate,and can be applied to the production process of polyether polyol. |
