为了对低碳链季铵盐进行定量分析,应用四苯硼钠返滴定法对<十二烷基二甲基氯化铵定量分析方法>(HG/T 2230-2006)标准中低碳链季铵盐质量分数进行了分析改进研究.以重量法为基准对分析结果的准确性进行了检验,通过测定结果的误差分析,对方法的重现性进行了探讨,同时对不同碳链季铵盐进行了定量分析.结果表明,当低碳链季铵盐分子的质量分数在0.1%以上时,应用<十二烷基二甲基氯化铵定量分析方法>(HG/T 2230-2006)标准分析低碳链季铵盐质量分数的改进方法重现性好,准确率为99.5%以上.

In order to make quantitative analysis for the short-carbon-chain quaternary ammonium salt, the method of "dodecyl dimethyl ammonium chloride quantitative analysis" in the standard(HG/T2230-2006)was improved and investigated by adopting the sodium tetraphenyl boron back titrimetry. Based on gravimetric method, the accuracy of the analysis results was inspected. According to the error analysis of the measuring results, the reproducibility of this improved method was discussed. Meanwhile, the different-carbon-chain quaternary ammonium salt was quantitatively analyzed. The result shows that as the mass fraction of short-carbon-chain quaternary ammonium salt molecular is more than 0.1%, the sodium tetraphenyl boron back titrimetry that improves the method in HG/T2230-2006 has good accuracy and repeatability, the accuracy rate of analysis result is above 99.5 %.
