> Is there a way to make PHREEQC report output in ppm rather than moles? There is no general switch to change the units. You can write Basic programs in USER_PRINT and USER_PUNCH that will write just about whatever you want. The following will write to the output file and the selected_output file respectively. USER_PRINT -start 10 PRINT "Ca, in ppm", TOT("Ca")*1000*40.08 -end USER_PUNCH -heading Ca_ppm -start 10 PUNCH TOT("Ca")*1000*40.08 -end > Also I'd like to run a simulation which will report the amount of ferihydrite precipitated from a solution THEN, using that amount of precipitate, perform sorbtion calculations. I've been running one simulation to find the amount of precipitate and then running the sorbtion reaction in a second simulation where I manually input the amount of precipitate formed in the first simulation using the Surface block. Is there a way to do this automatically in one step? You can link the number of sorption sites to the amount of a mineral. The mineral must be defined in "EQUILIBRIUM_PHASES n" and then in "SURFACE n" you put 'equilibrium_phase' and the mineral name as part of the data defining the surface. See the description of the SURFACE datablock in the users guide.
