摘要：

研究了用四苯硼钠滴定法测定季鏻盐 (TTPC)含量的新方法。该法在已知浓度的定量氯化钾溶液中,加入定量过量的四苯硼钠溶液,以季鏻盐 (TTPC)滴定剩余的四苯硼钠溶液。确定了最佳测定条件,并与经典方法磷钼酸喹啉容量法进行了比较,应用于样品测定,取得了满意的结果。

Abstract:

The titrimetric determination of TTPC has been studied by using sodium tetraphenyl boronate.Add quantitative and excessive sodium tetraphenyl boronate to KCl solution with definite concentration and quantity. Titrate the surplus Sodium tetraphenyl boronate solution with TTPC.The optimal determination conditions are determined .This method has been compared with classical volumetric method of quinoline phosphomolybdate. It has been applied to the determination of samples with satisfactory results.

Key words: titrimetric determination of sodium tetraphenyl boronate, determination, tributyl tetradecyl phosphonium chloride
