I've been doing tons of research on Fick's Law. I understand how to derive it and what its used for. I just need to see an example of it being used.

I need to use this equation to separate water from an alcohol and aromatic component.

Any help is greatly appreciated.

Chemeguy,

The law of Adolf Fick is a constitutive one that describes the molecular flux of a chemical specie. It can't be used to separate a mixture of water and alcohol; but plays a role in describing the process that does the separation.
You only need fick's law in separation processes that exploit differences in diffusion rates of various species.
For your system, I suggest you focus on Pervaporation- this is one process that could separate the mixture you have on the basis of diffusion rates.
