- W958512169 abstract "建立了离子色谱法同时测定磷酸二氢钾中P04^3-、Cl^-、F^-的方法,在12min内实现对3种阴离子的分离及同时测定,实验过程通过PO4^3-的含量计算磷酸二氢钾的纯度。在最佳实验条件下,建立3种离子的标准曲线,其r为0.9992-0.9999,检出限为0.051~0.30μg/mL,样品平均加标回收率为95.6%-104.5%,相对标准偏差为3.1%-4.9%。将测定结果与HG2321-1992((磷酸二氢钾》所规定的方法进行差异性分析,结果表明,实验所建立的方法与标准方法无显著性差异。该方法具有简单、快速、重现性好的优点,适用于磷酸二氢钾生产过程的工艺控制。" @default.
