Modeling linear sorption using phreeqc


How can I model linear sorption using phreeqc? I am trying to model alkali uptake by calcium silicate hydrate phases. Datawise I have the partitioning coefficient and I want to tell the software to take the alkali concentration from solution composition to calculate the uptake.

PHREEQC was designed to use DDL surface complexation, but it is possible to define linear sorption. Look at example 19 in the Version 3 user's manual. It's a little awkward, but doable.

Okay, thank you so much!
