Ozan Posted January 5, 2020 Share Posted January 5, 2020 Hey, I am trying to built a sorption database according to minerals and elements that I am interested in. I encounter so many surface complexation models such as; Constant Capacitance (CC), CD-MUSIC (CDM), Diffuse Double Layer (DDL), Extended Constant Capacitance (ECC), Ion Exchange (Iex), Non-electrostatic (NE), Triple Layer (TL), 1pK-Basic Stern (1pK-BS). I know that (from GWB Essentials) GWB can use two-layer surface complexation which includes constant capacitance, constant potential and Ion Exchange. My question is about DDL which is also double layer and I guess it is equal to constant potential. Is constant potential or DDL is a different model? Also, constant potential does not consider electrostatic interactions and NE also does not consider electrostatic interactions. So, is constant potential and NE are same models? I guess GWB does not model TL or CDM, could you please confirm that and give me more information if GWB can model any other surface complexation model. I am lost under many different names. I also checked out the book for these information but I couldn't find more. Here is the website I am using to find out the sorption data and these models (and explanation of models); https://www.hzdr.de/db/RES3T.login Thanks!
