Abstract
The migration of iodine on Beishan granite was studied by the dynamic column method using an UV detector. Migration parameters, such as distribution coefficient (Kd) and dispersion coefficient (Dd), can be obtained by fitting the breaking through curve. Kd was around 0.15 cm3 g−1 under all studied conditions except particle size. Dd was greatly influenced by the flow rate and eluent pH. The effect of speciation was not obvious. The appropriate I− concentration range for this method was 10−4–10−3 mol L−1. The results in this work are consistent with the previous works using radioactivity measurement.
