摘要
本文合成了两个酰胺型饱和漆酚双冠酰(Ⅰ、Ⅱ),饱和漆酚30-冠-10(Ⅲ)和二硝基饱和漆酚30-冠-10(Ⅳ),冠酰Ⅳ为新化合物。以这四种冠醚研制PVC膜铊离子选择电极,具检测下限,线性范围,选择性等性能都比较好。其中以Ⅳ制作的铊电极,检测下限可达6.31×10^(-7)mol硝酸铊,对钾离子的选择系数优于其它冠醚电极。
Four saturated urushiol type crown ethers were prepared and their thallium ino-selective electrode is described in this paper. These electrodes with newly synthetic saturated urushiol his-crown ethers(Ⅰ, Ⅱ,) saturated urushiol crown ether 30-C-10 (Ⅲ) and dinitrosaturated urushiol crown ether 30-C-10(Ⅳ) as electroactive materials were prepared and studied. This electrode based on crown ether Ⅳ exhibited lower limit of measurement 6.31×10^(-7)mol TINO_s, and selectivity of thise lectrode for K^+ is better than another electrodes.
