血清中氯的测定在临床检验上十分重要。常用的方法是二苯卡巴腙指示汞盐滴定法。这种方法不仅灵敏度低、需试样量较多,而且污染环境,对操作者有一定危害。近些年来,离子选择电极已广泛地应用于临床检验。但是对于血清或全血中氯的测定,固体膜氯电极由于蛋白质及其他有机物的沾污电位不够稳定;液膜氯电极又由于机械性能不佳及其他阴离子的干扰使用受到限制。于是,Hartman等人对液膜氯电极作了一些 Determination of serum chlorine in clinical testing is very important. Commonly used method is diphenylcarbazone hydrargyrum indicator titration method. This method not only low sensitivity, require more samples, but also pollute the environment, to the operator a certain degree of harm. In recent years, ion-selective electrodes have been widely used in clinical testing. However, for the determination of chlorine in serum or whole blood, the solid membrane electrode is not stable enough due to the stained potential of proteins and other organic substances. The membrane electrode is limited by the poor mechanical properties and the interference of other anions. As a result, Hartman and others made some of the liquid film chlorine electrode
