摘要
以乙醇-水混合液为溶剂,将聚醚多元醇样品直接溶解,然后用原子吸收分光光度计测定聚醚多元醇产品中的钾、钠离子含量。本法适用于聚醚多元醇样品中钾、钠离子含量均大于0.5×10^(-4)％的测定。本法操作简便,时间短,有利于进行生产现场分析。
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.
