Non-radioactivestrontium(Sr2+) was used to investigate the migration of radioactivestrontium in loess. The sorption and retardation characteristics of strontiumin loess were studied by batch tests and column experiments. The experimentalresults showed that the equilibrium sorption data for Sr2+ was fitting well tothe Freundlich isotherm models(r2= 0.97). And the Rd obtained frombatch experiment was larger than Rd determined by column test. The resultsindicated that Rd values derived from column tests are more accurate toevaluate transport of radionuclides in contact medium.
