本文制作了以4-苦胺基苯并-15-冠-5为活性物的涂丝运算放大器的钾离子选择电报,其对Na~+的选择性优于其它冠醚化合物的电极。可用低阻抗仪器测定电极的电位。本电极可用于测定土壤及植物中的钾含量。
In this paper, a potassium ion selective telegraph with a 4-acylaminobenzo-15-crown-5 as an active material was fabricated and its selectivity to Na ~ + was better than that of other crown ether compounds. The electrode potential can be measured with a low impedance instrument. The electrode can be used to determine the soil and plant potassium content.
