Interaction of H-3( ) (as HTO) and Cl-36(-) (as (NaCl)-Cl-36) with crushed granite and corresponding fracture infill material investigated in column experiments

Popis výsledku v původním jazyce

The transport of H-3(+) (as HTO) and Cl-36(-) (as (NaCl)-Cl-36) was investigated in the dynamic system, i.e., in the columns filled with crushed pure granite and fracture infill of various grain sizes. The aim of column experiments was to determine important transport parameter, such as the retardation, respectively distribution coefficients, Peclet numbers and hydrodynamic dispersion coefficients. Furthermore, the research was focused to quantification of the effect of grain size on migration of studied radionuclides. The experimental breakthrough curves were fitted by a model based on the erfc-function, assuming a linear reversible equilibrium sorption/desorption isotherm, and the above mentioned transport parameters were determined. The results showed that influence of grain size on sorption of H-3(+) and Cl-36(-) was negligible. Retardation and distribution coefficients of both tracers converged to one and zero, respectively, in case of all fractions of crushed granite and infill m
