Abstract

The sorption of nickel in 15 natural sediment-groundwater systems from Gor leben has been modeled using a simple surface complexation model. An apparent constant of nickel sorption has been computed taking into account the bulk cation exchange capacity of the sediment, the analytical composition of the groundwater and experimental sorption data obtained from related systems. The method of determining the prevailing surface complex has been described in detail, using changing properties of the natural systems. Competition from natural groundwater components for sorption sites has been taken into account.

The main parameters governing nickel sorption are cation exchange capacity of the sediment, together with ionic strength and pH of the groundwater. The model describes the influence of citrate on sorption and allows one to compare the varying sorption data of similar systems.

Computations were performed using the geochemical code MINEQL.
