Effect of grain size on the Sr-85(2+) sorption and desorption in columns of crushed granite and infill materials from granitic water under dynamic conditions
Original language description
The sorption of Sr-85(2+) in the form of 10(-6) M Sr(NO3)(2) in synthetic granitic water (SGW), and its desorption using the same radiotracer-free solution, were investigated under dynamic conditions in columns loaded with crushed granitic materials. Thegoal of study was to evaluate the influence of grain size on the retardation (R) and distribution (K (d)) coefficients of the soluble Sr-85(2+), as well as on the other transport parameters type of Peclet number (Pe) and hydrodynamic dispersion coefficient (D (d)). Pure granitic sample and granitic fissure infill samples were used, crushed and sieved into 4 different grain size from 0.063 to1.25 mm were used. In order to determine migration parameters, the model based on erfc-function was used, assuming reversible equilibrium linear or non-linear (Freundlich) sorption/desorption isotherms. By means of both model approaches, the experimental breakthrough curves were fitted using non-linear regression procedure according to Newton-Raphso
