摘要: Investigation of reactions between neptunium and soil samples representative the saline area around Gorleben salt dome (Federal Republic Germany) was conducted to obtain an understanding transport mechanism in saturated brine aquifers. Leaching /sup 237/ Np-doped glasses with under oxic conditions resulted release soluble species Np(V). Adsorption parameters obtained from application nonlinear sorption isotherms static experiments were used interpret migration through columns. The existence two different adsorption sites reacting at rates postulated. Retardation factors anoxic measured. In environments such as those found undisturbed repository horizons, more activity fixed by soil.
