|Alfisol, Item 007:|| IExFit, version 3.1
Fit adsorption data based on ion exchange reaction models.
Display solid & liquid & gas phase speciation diagrams as a funciton of pH.
Here you view your model results and optimimize your model to fit your adsorption data.
You can choose which part of the model you wish to use or ignore (checkbox "use"), which Γmax value(s) you wish to optimize, and which pK value(s) you wish to optimize. You can also choose which data set to use for your optimization criteria (checkbox "Fit").
In the example shown below,
.... black = H(+) adsorption data and IExFit model results
.... blue = Cl(-) adsorption data and IExFit model results
.... green = phthalate adsorption data and IExFit model results
Notice how well all three data sets were predicted using one ion-exchange competitive model.
