kelvin Posted December 9, 2010 Share Posted December 9, 2010 Hi, I use GWB pro. 8.0 to built the Eh-pH diagram of Fe in the presence of Cl-, the input informations are as follows: # Act2 script, data = "c:\program files\gwb\gtdata\thermo.dat" verify swap e- for O2(aq) diagram Fe++ on pe vs pH log activity main = -6 log activity Cl- = -.79 speciate Cl- x-axis from 0 to 14 increment 1 y-axis from -16.9 to 16.9 increment 2 When I change the temperature condition(ex. 24.9C, 25C, 25.1C), the results seem the same(fig(a)~©). But when I change the database(thermo.com.v8.r6+), the results seem different(fig(d)~(f)). Why?? Thanks a lot. Quote Link to comment Share on other sites More sharing options...
