Magnesium Ion Selective Electrodes Based on β-Diketone Compounds
The ion selectivities for poly(vinyl chloride) (PVC)-matrix membrane ion-selective electrodes based on seven lipophilic diketone compounds were examined. All the electrodes based on the tested five β-diketone cómpounds exhibited clear Mg 2 ′-selectivity under high pH conditions (pH10). Especially, t...
