摘要
研究了以 5种新型酰胺型三脚架有机化合物为载体的PVC膜电极对碱金属和碱土金属阳离子的响应行为 .比较了这 5种三脚架化合物的结构对电极响应性能的影响 .结果表明 ,不含较大萘环的配体适于作为离子选择电极的载体 ,所制电极可作为Li+ 或Ca2 + 选择性电极 .当电极膜中增塑剂的极性较大时 ,有利于电极对二价离子的响应 .若配体中基团的体积较大时 ,则不利于配体对金属阳离子的络合及所形成络合物在膜相中的流动 .
The response behaviors of ion_selective electrodes prepared by five novel amido tripodal compounds are investigated.The effect of the structure of the ionophores on the electrode response is studied comparatively.The experimental results show that the studied ligands,which have no larger naphthalene nucleus,can be used as ionophore.The prepared electrodes are used as Li + and Ca 2+ ion_selective electrodes.The more polar plasticizer might enhance the response of electrode to the divalent ions.The ligands,which have larger functional group,are not in favour of ligands binding to metal ions and the fluidity of the complexes.
