A NEW TYPE OF ION-SELECTIVE ELECTRODE FOR NONAQUEOUS SOLUTION

A new type of ion-selective electrode-water membrane system is proposed and an assumption of water membrane is confirmed. A NdCl_3 water membrane electrode has be- en made te demonstrate its applicability to the determination of Nd (PMBP)_3 (PMBP=1- phenyl-3-methyl-4-benzoyl-5-pyrazolone)in cyclohexanone. Conditions for stabilizing potential of reference electrode in nonaqueous system are optimized. It is observed that the potential response on the surface of two immiscible solution is bidirection...
