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)?...

Which parameters or data are reuired to model reactive transpoet modeling of reduced nitrtae by adsorbrnt by Phreeqc or any other suitable one?

To reduce nitrate leaching in soil, sorbents would be used to stop them. Now I am beginer in geochemistry and don't know how to do relevant chemical experiments? And which data I need to couple...
