| Abstract: |
The dependence of sorption distribution coefficient (K
d) of Np(IV) for illite, shale and MX-80 was investigated as a function of pHc and ionic strength (I) under high ionic strength, reducing conditions. The overall trends of Kd on three solids were independent of pHc at 5 ≤ pHc ≤ 10 and I at 0.5 M ≤ I ≤ 6 M. The surface complexation constants of Np(IV) sorption on illite and MX-80 were estimated by the 2 SPNE SC/CE model. The sorption model well predicted the pHc dependence of Kd, but could not completely describe the ionic strength dependence. |
