摘要
本文提出交流示波极谱滴定用于四苯硼钠滴定十六烷基三甲基汉化铵(CTMAB)、溴代十四烷基吡啶(TPB)、氯代十六烷基吡啶(CPC)。以(dE/dt)-E曲线上NaTPB的切口消失指示终点。方法准确、灵敏、简便、快速。
AC oscillopolarographic titration can be applied advantageously to the titration CTMAB, TPB, CPC with sodium tetraphenylborate (NaTPB). NaTPB is added to precipitate quantitatveily CTMAB, TPB, CPC aqueous solution, The excess of NaTPB in the filtrate is titrated with thallous sulfate standard solution, using the disappearance of the incisian of NaTPB on dE/dt—E curve to indicate the end point of titrations. The method is accurate, sensitive, rapid and simple.
