Is it possible to perform batch experiments with three components, two solutes and soil?

I am not sure how it is possible to see the interaction of two solutes on each other and soil particles! So I like to do batch experiments firstly but what I have seen so far isotherms are fitted...

How to model nitrate capture (sequestration) by a nanocomposite in a soil column?

As it is seen in literature, the ADE with a (dS/dt) is used to model a reactive transport. However, how it can be modeled if nitrate as one solute is stuck by another solute (e.g. nanoparticles)?...
