Processes for preparing ion selective membranes are presented which have selectivity for a primary analyte (in particular magnesium) as well as another ion (in particular calcium), wherein said process comprises addition of a) an ionophore (in particular 1,10- phenanthroline), b) a lipophilic salt containing said primary analyte (in particular hemi-magnesium bis[4-octylphenyl]phosphate) and c) a lipophilic salt containing said other ion (in partricular hemi-calcium bis[4-octylphenyl]phosphate). Also, ion selective membranes are presented which are prepared using said processes, in particular to membranes selective for magnesium ions. In further aspects, electrodes and potentiometric sensors are presented comprising such membranes and the use thereof for determining ion concentrations in samples.
