Y. Kitatsuji et al., Plutonium(III)-ion selective electrode of liquid membrane type using multidentate phosphine oxide ionophore, ANALYT CHIM, 387(2), 1999, pp. 181-187
Plutonium(III)-ion selective electro de consisting of phosphine oxides such
as bis-(diphenylphosphoryl) -methane as an ionophore was developed. Fundam
ental data, which were utilized for designing the electrode, on the ion tra
nsfer of Pu3+ across aqueous (w)/organic (org) solutions interface facilita
ted by the phosphine oxide derivatives were obtained by ion-transfer polaro
graphy at the w/og interface. The Pu(III)-ISE prepared exhibited Nernstian
response to the concentration of Pu3+ in the sample solution. Interference
of UO22+, U4+, NpO2+ and Pu4+ was investigated. (C) 1999 Elsevier Science B
