Batch adsorption and column experiments were conducted to investigate the effect of clay colloids on the transport behavior of \ce{Cs+} in soil columns. The results indicate that the adsorption of \ce{Cs+} onto clay colloids follows the Freundlich isotherm and pseudo-second-order kinetics. The adsorption is spontaneous and exothermic, strongly influenced by pH and coexisting ions. The promoting effect of clay colloids on \ce{Cs+} transport in soil columns depends on the proportion of \ce{Cs+} adsorbed onto colloids.
