Abstract Direct thermal parametric pumping separations of a NaCl‐H 2 O‐ion retardation resin system have been investigated. Experimental breakthrough curves and batch parapump runs were used to determine the lumped‐parameter mass transfer coefficient λ and its dependence on velocity and temperature. Computer simulation of additional batch runs verified both the model and the STOP‐GO algorithm used to solve it. Computer estimates of open‐system behavior are presented.
