聚苯硫醚生产过程中锂含量的测定方法

Determination Method of Lithium Content in PPS Production Process

介绍了采用重量法测定聚苯硫醚(PPS)生产过程的物料中锂含量的方法。通过实验发现,该方法相对标准偏差RSD<1.0%(n=7),氯化锂回收率在99.6%～104.5%,方法的精密度和准确度较好,能够满足生产的要求。

This article described the polyphenylene sulfide in the production process,the lithium content in the gravimetric determination of materials.Found through experiments,the relative standard deviation（RSD）1.0%（n=7）,the standard addition method recoveries were 99.6~104.5%,the precision and accuracy of the method was better and able to meet production requirements.
