Suvena:

I read your proposal. I think that I misunderstood before. I see that
you just wanted the pulper to make the paper fibers to be able to study
adsorption on them. This is fine. Other points: make sure that you
have good temperature control and that the temperature is the same as
the hardness tolerance phase boundary is at since it is crucial that you
not have precipitate present after adsorption is equilibrated. Also, you
will want to use as high of a solid/solution ratio as possible to get as
high of a concentration change as possible. Please pass on to my other
adsorption student also.
