摘要
研究了在Na2 CO3-NaHCO3缓冲体系下 ,以饱和甘汞电极为参比电极 ,氟硼酸根离子选择性电极为指示电极 ,用季盐溶液滴定过量四苯硼钠测定季盐含量的新方法 ,确定了最佳测定条件。本方法简便、快速。
TTPB was determined by potentiometrically titrating excess sodium tetraphenyl borate with TTPB,using a saturated calomel electrode as reference and a [BF 4] - ion-selective electrode as indicator in Na 2CO 3-NaHCO 3 buffer solution.The optimum conditions were determined.The method is rapid and accurate.
