Complete self-contained system in zipped folder. Surely the quickest way to get up and running is to download a complete example in a single zipped folder (ca 360 kB ) that includes the ORCHESTRA executable, the object database, a thermodynamic database and input files defining a simple example system.
The model employs a pre-defined set of components that includes free ions such as Na+ and neutral and charged complexes (e.g., H4SiO4, Cr(OH)2+).
The pH-dependent adsorption of U(VI) on MSD were simulated by using the surface complexation modeling employing diffuse layer model with the aid of Visual MINTEQ codes. Diffuse layer model assumed that amphoteric hydroxide functional groups (SOH) can be reacted with U(VI) species from aqueous solutions.
