Re: phreeqc problem




The only way that I can think of is to recalculate the pe in USER_PUNCH.
The following is an example for iron. You would have to code an equation
for each redox couple.

David


SOLUTION 1
      temp  10
      pH    5
      pe    4
      Fe(2) 1
      Fe(3) 1
USER_PUNCH
      -heading  pe_Fe(2)/Fe(3)
10 pe_fe = LA("Fe+3") - LA("Fe+2") - LK_SPECIES("Fe+3")
20 PUNCH pe_fe
END
