被引用回数：11 パーセンタイル：64.04(Chemistry, Analytical)A new mutual separation method was developed to enable the analysis of Zr, Nb, and Mo in radioactive contaminated water from the Fukushima Daiichi Nuclear Power Station (FDNPS). First, distribution coefficient (
) values between Tetra Valent Actinide (TEVA) resin, and HF, HF/HNO
, and HF/HCl solutions were obtained to select the conditions for chromatographic separation. The separation performance of the developed method was validated with a control sample, which contained elements that could be interfere with the measurement of Zr, Nb, and Mo, (Cr, Co, Ni, Ge, and Se) and non-radioactive elements of high-dose nuclides in the contaminated water (Cs, Sr, and Y). The scheme was also evaluated with a simulated seawater sample because seawater was injected into the damaged reactors to assist cooling in the early stages of reactor failure. Finally, the chromatographic separation method was applied to the analysis of Zr, Nb, and Mo in contaminated water sampled at the FDNPS.

被引用回数：19 パーセンタイル：55.23(Biochemical Research Methods)In order to analyze Mo in rubble samples from the Fukushima Daiichi Nuclear Power Station, a separation method for Mo from Zr, Nb, and the other major elements of the rubble samples was developed. Firstly, loss of Mo during the digestion of simulated rubble samples was evaluated. Next, weight distribution coefficients (
's) of Zr, Nb, and Mo between an extraction chromatographic resin (TEtra VAlent actinide resin, TEVA resin) and acid solutions (HF-HCl and HF-HNO solutions) were determined to obtain suitable solution conditions for the separation of Mo from Zr and Nb. Based on the obtained 's, a chromatographic separation scheme was designed and applied to the digested solution of the simulated rubble sample.
