✦ Synopsis
Investigation of the interaction of neutral carriers with ions in membranes by ^13^C‐NMR. and EMF.‐measurements.
Applying a simple model, information on the interaction of neutral carriers with cations as well as on the ion pair formation may be obtained through ^13^C‐NMR. and potentiometric studies of PVC‐supported ion selective liquidmembranes in contact with aqueous solutions. The results indicate that carriers for K^+^ (nonactin) and synthetic ionophores for Ca^2+^ show an association of the carrier‐complexes with lipophilic anions. The extent of complex formation of the carrier in the presence of lipophilic anions in the sample solution is in agreement with earlier interpretations of the anion interference of cation selective liquid‐membrane electrodes.
