Two approaches are considered in this work:\r\ncolumn experiments and simulations. A software called OPTIPUR\r\nwas developed, tested and used. The approach simulates the onedimensional\r\nreactive transport in porous medium with convectivedispersive\r\ntransport between particles and diffusive transport within\r\nthe boundary layer around the particles. The transfer limitation in the\r\nboundary layer is characterized by the mass transfer coefficient\r\n(MTC). The influences on MTC were measured experimentally. The\r\nvariation of the inlet concentration does not influence the MTC; on\r\nthe contrary of the Darcy velocity which influences. This is consistent\r\nwith results obtained using the correlation of Dwivedi&Upadhyay.\r\nWith the MTC, knowing the number of exchange site and the relative\r\naffinity, OPTIPUR can simulate the column outlet concentration\r\nversus time. Then, the duration of use of resins can be predicted in\r\nconditions of a binary exchange.","references":"[1] F. Helfferich, Ion Exchange, McGraw-Hill, New York, 1962, pp. 5-9.\r\n[2] F.
