Field tests on Ce transfer in natural loess environments

Tanaka, Tadao ; Mukai, Masayuki ; Bamba, Tsunetaka

Migration behavior of Ce, one of redox-sensitive elements, was studied in natural aquifer loess zone in P.R.China. Migration parameters such as distribution coefficient were obtained by column migration and batch sorption tests. The batch sorption test indicates Ce is irreversibly incorporated near loess surface as Ce(IV). Cerium showed large retardation in migration in the aquifer loess zone. Predicted migratory mobility of Ce in the aquifer, which was calculated by using the distribution coefficient determined by the batch and column tests, could reproduce that in the field test conservatively.
