    • -3 M. The potential was found to remain constant from pH 1.99 to 5.40. Beyond pH 5.40, the potential was found to decrease due to the formation of hydroxyl complexes of uranyl ions. At pH <1.99, the membrane suffered strong interference from hydrogen ions due to protonation of the ionophore.

    • Different plasticizers were used to study their effect on the potentiometric response of the electrode (E1). The plasticizers used in the present study were tributyl phosphate (TBP), dioctylsebacate (DOS), o-nitrophenyloctyl ether (o-NPOE), dibutylphthalate (DBP), bis(2-ethylhexyl)adipate (DOA), dioctyl phthalate (DOP). Electrode (E1) with TBP as plasticizer was selected for further studies, as it gave a near-Nernstian slope over a wide concentration range, as compared to other membrane electrodes.
