| 摘 要： | 目的比较滴定法与高效液相色谱法检测消毒剂中醋酸氯己定含量的准确度与系统误差。方法应用JJF1059-1999《测量不确定度评定与表示》中的评定理论进行了测量不确定度比较。结果滴定法与高效液相色谱法测得的消毒剂中醋酸氯己定浓度分别为1.99 g/L及2.02 g/L,扩展不确定度U95分别为0.05 g/L及0.08 g/L,均在可接受的误差范围之内。严格控制环境温度在20℃,使用A级量具有利于提高滴定法的准确度。控制标准曲线的制作过程,有利于提高高效液相色谱法检测结果的准确性。结论滴定法检测消毒剂中醋酸氯己定含量不确定度低于高效液相色谱法,通过控制测定条件可提高检测结果的准确性。
