近年来应用中性载体作为Ba~(2+)离子选择性的活性物质,已有了较多的研究。本文将着重讨论非离子型表面活性剂,三(苯乙基)苯基聚氧乙烯基醚为活性物质的钡电极的某些性能。电极可直接用于Ba~(2+)离子的电位测定,以及在各种能与Ba~(2+)离子形成沉淀的哪些阴离子(SO_4~(2-)、CrO_4~(2-)、C_2O_4~(2-)等)的滴定中作为指示电极。实验部分 1.电极的响应时间和稳定性:电极插入10~(-2)M的BaCl_2溶液中,观察电极的电位值随时间的变化。实验结果,电极的响
In recent years, the application of neutral carrier as Ba 2+ ion-selective active material, has been more research. This article will focus on the non-ionic surfactant, tris (phenethyl) phenyl polyoxyethylene ether as the active material of the barium electrode of some of the properties. The electrode can be directly used for the determination of the potential of Ba 2+ and for the determination of which anions (SO 4 2-, CrO 4 2-, C 2 O 4 ~ (2-), etc.) as the indicator electrode. Experimental part 1. Electrode response time and stability: The electrode was inserted into 10 ~ (-2) M BaCl 2 solution and observed the change of electrode potential value with time. Experimental results, the electrode ring
