Description
The sorption properties of U(VI), 90Sr, 137Cs, 239Pu(IV), 241Am, 237Np(V) on bentonite and U(VI), 137Cs and 90Sr on zeolite have been investigated. The Kd values, Rf values, migration rates and sorption isotherms were determined using batch and column tests. The effect of contact time, particle size, pH, concentration, composition of sorbents and ratio of solid to solution on the Kd values has been examined. In order to explain the results obtained, the chemical composition, cation exchange capacity, specific surface area, bulk density, pore diameter, effective channel size, effective porosity, permeability coefficient, thermal stability and degree of swelling of materials studied were also determined. The results obtained show that Na- and Ca- bentonite taken from Lin An and An Ji deposits and clinoptilolite and mordenite taken from Jingyun deposit are suitable backfill material for HLW underground repositories.
