Two physical non-equilibrium based and one chemical non-equilibrium based solute-transport models were used to determine sorption processes of uranin with aquifer materials by evaluating their rate parameters.
This was necessary to know the underlying sorption process(es) of uranin with the Krauthausen aquifer materials.
The concentration of uranin in the monitoring wells differed considerably at different samplers.
The evolution of uranin and bromide, although monitored in 58 observation wells, was detected in 29 wells of which only 17 provided almost complete BTCs.
The small mass-transfer coefficient, [alpha] = 0.03/day (Eqn 9), being the result of rate-limited mass transfer between the mobile and immobile water phases, and the large equilibrium distribution coefficient, [k.sub.d] = 0.32 (Eqn 14), of uranin demonstrate the presence of kinetic sorption reactions.
Variation of velocity with travel path of uranin plume
2, the travel time of the uranin plume increases with increasing travel path of the plume at an increasing rate due to nonlinear sorption of uranin with the aquifer materials.
First, [gamma] closely agrees with the mean value of n (= 0.69) (Eqn 15) determined by asymptotic analysis of column BTCs of uranin (Vereecken et al.
