Abstract

A semi-implicit iterative operator splitting method for modelling transport with ion exchange is developed and implemented in a numerical one-dimensional code. The method is tested against a linear exchange (sorption) example for which, theoretically, the need for iteration is absent. The numerical code is used to simulate an aquifer sediment column experiment with binary ion exchange. For this example the semi-implicit method was a factor of 3 faster than the explicit method. The method therefore seems promising for interpreting these types of experiments.
