利用碘-三辛胺盐酸盐反应分光光度测定TOA·HCl
Determination of Trioctylamine Salt by Spectrophotometric Iodine Method
【摘要】 研究了测定三辛胺盐酸盐(简称TOA·HCl)的一种新方法——碘光谱法.TOA·HCl在四氯化碳溶液中与碘生成电荷转移化合物,该物质的最大吸收波长为370nm.TOA·HCl在0~4×10-4mol·L-1范围内符合比耳定律.该方法准确、简便、快速,其它溶剂的干扰较小,回收率在94.5%~101.9%,能够满足分析的需要.
【Abstract】 A new method for determination Tri n octylamine salt (TOA·HCl) by spectro photometric iodine method has been studied in this paper.TOA·HCl reacted with Iodine in the solution of CCl 4 to produce electron transfer complex.The maximum absorbance of the complex was at 370nm.Beer’s law was obeyed in the range of 0 ̄4×10 -4 mol·L -1 for TOA·HCl. The method was sensitive, simple, rapid and the interference of the other solvents was little.The recoveries were between 94.4% ̄101.9%. It can satisfy the requirement of analysis perfectly.
