The absolute mobility of NpO2+ and its equivalent ionic conductivity were extrapolated at 25degreeC and at infinite dilution using a set of experimental data obtained at various ionic strengths. The separation was carried out by capillary electrophoresis (CE) at various concentrations of creatinine at a pH of 5. The detection of NpO2+ was performed by inductively coupled plasma mass spectrometry coupled on-line with CE. The following values have been found: muNpO2+0(25degreeC)=(2.94+-0.07)cntdot10-4 cm2 V-1 s-1 and LAMBDANpO2+0(X104, 25degreeC)=28.3+-0.7 m2 S mol-1.
