| 摘 要： | 研制了一种测定馏分燃料油中硫醇硫的分析仪器，实现了整个测试过程的自动化。测量采用电位滴定法，完全符合国家标准GB／T1792的要求。滴定过程由软件控制，采用两段动态等量精确滴定方式，终点附近滴定体积始终为0．02mL，并能自动往复和识别终点。测定结果相对标准偏差为2．0％，与手工电位滴定法结果一致。

| Abstract: | An analyzer was designed for the determination of mercaptan sulfur in fuels with the measurement process fully automated. The measurement is based on the principle of potentiometric titration and is in consistent with the Chinese national standard GB/T 1792. The whole titration process is controlled by software and two-step dynamic constant increment titration method is used. The increment of titrant is constantly 0.02mL when nearing the end point which is identified repeatedly and automatically. The RSD is 2.0% and the test results are in good agreement with those obtained by manual method. |
