离子选择电极法测定氟离子的影响因素分析

Analysis of Influencing Factors on the Determination of Fluoride by Ion Selective Electrode Method

根据氟离子选择电极法检测氟离子的原理,系统分析了使用方法检测氟离子过程的影响因素。认为分析工作者需对该检测方法的基本原理和检测体系有充分了解,检测过程需控制好缓冲溶液的选择、电极的空白值、样品溶液的pH值以及搅拌速度和时间,以减少检测过程不良因素带来的影响,提高检测工作的效率和检定结果的准确度。

According to the principle of fluorine ion selective electrode method, the influence factors of fluorine ion were analyzed by using the modified method. Analysts believe that workers should analyze the detection method and detection system of the basic principle of a full understanding of the blank selection, electrodes control the buffer value, the pH value of sample solution, the stirring speed and time, in order to reduce the adverse factors influence the detection process, improve the efficiency of testing and verification results accuracy.
