摘要
研究了应用自动电位滴定仪对肥皂中氯化物含量进行快速测定的实验方法,并对5个协同实验室间的比对检测数据,按照国家标准GB/T 6379.2-2004进行了统计分析,得到方法的重复性标准差为0.0032%,再现性标准差为0.013%。加标回收率为98.5%~100.6%。实验结果表明,该方法具有快速、准确、抗干扰能力强等优点。
This article studied a rapid method of testing chloride content in soap using automatic potentiometric titrator.The statistical analysis was carried out according to the national standard GB/T 6372.2-2004 standard through the detection data of 5 collaborative laboratories,the reproducibility standard deviation of the method is 0.0032%,the reproducibility standard deviation is 0.013%,the recovery rate is:98.5%-100.6%.This method has the advantages of fast,accurate and strong anti-interference ability.
