The mass of solute removed (dm) is given by


where (Ct) is the concentration of solute in the vessel after time (t).

The mass change (dm) will result in a change in concentration (dCt)



where (Q) is the flow rate,
(v) is the volume flow of mobile phase through the system after time (t)
and (k) is the integration constant.
