Dear Jia, I have figured out the log K problems for TC, but still have problems when given the other ion species. The detail process is in the attachment files, I have closed the precipitation this time, but still struggled here. I wish I can get some guide to make it. Best wishes Cheng TC-CaMg.rea thermo-TC_1.tdat

Hello Jia, logK 9.3 is really a wrong value, which is the newest change we tried, and the right log K value is really the 16.57. In addition, we don't need any surface adsorption here, so I give a really small value to the porosity. I think I have control the condition well and they are same as I tried in Mingteq, but I get a wrong result. I can't get the solution from your suggestions. Did there any other problems I have made here? I'm looking forward to hearing from you. Thank you again, Cheng Zhang

Dear Jia, I have added a new chemical, Tetracyclin, into the thermo-TC_1.tdat, and the detailed equilibrium equations were all prepared in the new thermo data. But the species-pH results were not the same as the reference showed. I have checked by using the Mingteq, the Mingteq results were the same as the reference. I have no idea about this error. Please give us some suggestions or some guide. Thanks a lot Cheng thermo-TC_1.tdat TC-pH_test1.rea
