摘要
磷酸酯抗燃油中活性氯含量的准确、高效测定,对电液控制系统安全稳定运行很有意义。对自动电位滴定方法测量磷酸酯抗燃油中活性氯的原理、仪器设备、检测条件进行了研究;组织了8个实验室、5个样品的协同试验,并对结果进行评价。依据重复性、检测限、回收率及精密度等技术指标,所研究制定的自动电位滴定法检测磷酸酯抗燃油活性氯含量精密度高,检测效率高,且样品处理简单、仪器配置要求不高、分析速度快,可以在电力行业中推广应用。
The detection of active chlorine content in the phosphate ester fire-resistant fluids is of great importance for the electro- hydraulic control system.In this paper,the principles,instruments and operating conditions of automatic potentiometric titration method to detect active chlorine content in the phosphate ester fire-resistant fluids are studied.The inter-laboratory experiments involving eight laboratories and five samples are conducted and the results are evaluated.In terms of repeatability and reproducibility,limit of detection,recovery rate and accuracy of measurement,the proposed automatic potentiometric titration testing method is capable of detecting the active chlorine content in the phosphate ester fire-resistant fluids with high accuracy and efficiency as well as fast analysis of measurement but simple sample treatment procedures and low requirements for instrument configuration.Therefore it can be promoted for practical usage in the field of power industry.
