PVC-Membrane Potentiometric Electrochemical Sensor Based on 2-(4-Oxopentan-2-ylideneamino)isoindoline-1,3-dione for Selective Determination of Holmium(III)

2-(4-Oxopentan-2-ylideneamino) isoindoline-1,3-dione (OID) was found to be a suitable neutral ionophore in the fabrication of a highly selective Ho3+ membrane sensor. The electrode has a near-Nernstian slope of 19.6±0.5 mV per decade with a wide concentration range between 1.0×10-6 and 1.0×10-2 mol/...
