preparing a new data set for sorbing surface

[JohannaRuether]

Hi,

 

I´m trying to create a new data set for sorbing surfaces that deals with the sorption of calcite on quartz minerals.

 

I´m not very familiar to the complaxation modelling.´, that´s why I´m not very sure if I prepare the correct data set.

 

Attached I send two different files, in the first one the basis species is CaCO3 and it runsin Spec8 and React correctly. But I cannot enlarge thespecific surface area of quartz above 0.1 m2/g.

The second file, where CaOH ist the basis species does not run in pec8 nor React at all.( error message: Dataset is incomplete! last line read is line 63: > log K= 13.9107 dlogK/dT= 0.0000

 

 

Please give me supoort by finding the correct way to modell the sorption of Calcite onto SiO2.

 

Thank you,

 

Johanna
