采用离子选择性电极测定分析样品是一种很有发展前途的分析方法。这种分析方法能在有各种离子存在的较复杂溶液中有选择性地、直接迅速地响应某种特定离子活度、而不需要作繁杂的样品预处理,这是诸如极谱分析、色谱分析等仪器手段所不及的。我们通过大量的实验,对国产电极CSB—C1—2型、CSB—I—1型电极性能及其应用于塑料厂大气监测和水体监测的方法等问题进行了初步的探讨,取得了一定的成果。 一、氯、碘电极性能及其准确性的测试 电极的选择性及宽的线性工作范围是离
Analytical samples using ion-selective electrode assays are a promising method of analysis. This method of analysis can selectively and directly respond to a specific ion activity in more complex solutions of various ions without the need for complicated sample pretreatment, such as polarographic analysis, chromatography Analysis and other instruments beyond the reach of. Through a large number of experiments, we conducted a preliminary study on the performance of domestic electrode CSB-C1-2 and CSB-I-1 electrodes and their application to atmospheric monitoring and water body monitoring in plastic factories, and achieved some results . A, chlorine, iodine electrode performance and accuracy of the test electrode selectivity and wide linear range of work is
