The construction and performance characteristics of uranyl membrane electrodes based on cheap and commercially available amino(trimethyl)phosphate are described. The influence of various membrane constituents on the potentiometric responses of the prepared membrane electrodes has been studied. Optimized membrane electrodes exhibited performance characteristics comparable with those based on high cost and commercially available ionophores. Selectivity studies indicated that the developed membrane electrodes are selective towards uranyl ion over a large number of cations including the well-known uranyl ion interferents (e.g., Fe3+, Th+4). The analytical utility of the proposed membrane electrode has been demonstrated through its application in nuclear safeguards verification purposes.
