A new mutual separation method was developed to enable the analysis of 93Zr, 94Nb, and 93Mo in radioactive contaminated water from the Fukushima Daiichi Nuclear Power Station (FDNPS). First, distribution coefficient (Kd) values between tetra valent actinide resin and HF, HF/HNO3, and HF/HCl solutions were obtained to select the conditions for chromatographic separation. The separation performance of the developed method was validated with samples containing potentially interfering elements of the measurement of 93Zr, 94Nb, and 93Mo. Finally, the chromatographic separation method was applied to the analysis of 93Zr, 94Nb, and 93Mo in contaminated water sampled at the FDNPS.
