Re: co2 partial pressure




> how can I calculate the partial pressure of co2 with hydrochemical data
by phreeqc computer program?

The log PCO2 is equal to the value printed for the saturation index of
CO2(g) in the PHREEQC output. The value should be printed for all
calculations, including initial distribution of species calculations
(whenever SOLUTION data are defined).
