@ lon-selective compositions which comprise an ionophore, a compound capable of solvating the ionophore and a supporting matrix are disclosed. The ionophores useful in these compositions are certain crown ethers. These ion-selective compositions are particularly useful as ion-selective membranes which are capable of selectively transporting a first ion in preference to a second ion. Dry-operative electrodes using these ion-selective compositions as membranes are also disclosed.
本研究公开了一种离子选择性组合物,该组合物包括一种离子团、一种能够溶解该离子团的化合物和一种支撑基质。 这些组合物中有用的离子团是某些
冠醚。 这些离子选择性组合物作为离子选择性膜特别有用,它能够选择性地传输第一种离子而不是第二种离子。 本研究还公开了使用这些离子选择性组合物作为膜的干式操作电极。
