交流示波极谱滴定分析方法研究

Investigation into AC-Oscillopolarographic Titratiou

本文用四苯硼钠在交流示波极谱图上的切口消失指示终点,测定阳离子表面活性剂季胺盐、烷基吡啶盐的分析方法。该方法简便,快速,终点灵敏,精度好,结果准确。

It is shown that AC-bsc il lopolarog raph i c titrat ion can be sael usecessf-ully to measure CTMAB TPB and CPC Teiraphenyborate of sod ium (NaTPB)is added to prec ip i tat e CTMAB or TPB or CBC guaat itat iv ely from an agueous s-ojut ion. Af t er fil t ra t ion, h e exiess of NaTPB in the filtrate is titrated with a standard colution. of thallous sulphate,ind the end of titratian is;indicated by the disappearance of the incision of NaTPB on the dE/dT-E Curve.The m-ethod described is rapid ,tecuratle,-ens i t i ve,and convon ient for use.
