Different membrane compositions were studied. The selectivity coefficient found was 0.71, independent of the membrane composition. This proves the robustness of the ISE method for testing the enantiomeric selectivity of newly synthesized ionophores. Selectivities of the new ionophore towards different hydrophilic cations were also determined. Key Words: ion-selective electrodesenantiomer-selectivitychiral crown ether ionophoreRead More
