Various synthetic zeolites (KL, LZY, 13X, and mordenite), as well as a natural zeolite (clinoptilolite) were evaluated for the uptake of uranium from solution. Mordenite, LZY and KL were most effective for uranium uptake. The relative effectiveness of the zeolites was a function of their pore dimensions, chemical compositions and cation concentration. Mordenite showed superior performance to a clay-soil for uranium uptake. With time, initially sorbed uranium later re-dissolve from the clay, but remained anchored in the matrix of the zeolite. Mordenite therefore demonstrated potential for use as an in situ trap for preventing uranium migration in soils.
