STUDY OF NUCLIDE MIGRATION OF FISSION PRODUCTS Ⅰ . SORPTION OF IODINE ON CONCRETE

In this paper the sorption (desorption) behaviour of iodine on the concrete with the simulated groundwater and the sorption isotherm were studied. The value of distribution ratio RDa at 30±2℃,C1 = 10-6mol/l and pH=9. 01 was determined to be 3. 16±0. 32 ml/g. The effects on RD values of acidity, solid-liquid ratio,solid specific surface area and the reductant (Fe and (NH2)2) were also investigated.
