Abstract
Ion-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 in ion-selective membranes and electrodes which are capable of selectively transporting a first ion in preference to a second ion. Such compositions, membranes and electrodes are useful for potentiometric measurement of alkali metal ions, e.g. lithium, sodium and potassium, in aqueous solutions, e.g. biological fluids. Dry-operative electrodes using these ion-selective compositions as membranes are also disclosed.
