摘要
研究复合季铵盐消毒剂含量的测定与滴定误差分析。探讨了四苯硼钠标准液配制及对滴定分析终点颜色的影响,并与单季铵盐定量分析方法进行了对比。结果表明:四苯硼钠两相滴定法适合于复合季铵盐定量分析,但要注意四苯硼钠标准液配制的正确性及滴定终点颜色的判断。
The method for determining the content of compound quaternary ammonium disinfectant and its titration error analysis were investigated. The influence of color change at the end point of titration and preparation of four benzene boron sodium standard solution were explored,and the mono quaternary quantitative analysis methods were compared. The results revealed that the four benzene boron sodium two-phase method was suitable for quantitative analysis of compound quaternary ammonium salt,but attention should be paid to the preparation of four sodium benzene standard solution and the determination of the color change at the end point of titration.
