CHEAQS Next is a computer program for calculating CHemical Equilibria in AQuatic Systems. You supply input data, the program calculates the chemical speciation for you. CHEAQS Next is free but it is not cheap.
Features
- You can calculate the concentration of complexes, but you can also calculate:
- redox equilibria;
- complexation by natural organic matter (3 different models developed by Tipping and co-workers: Model V, Model VI and Model VII;
- solids that are formed due to oversaturation (or just calculate if they are oversaturated or not);
- adsorption (surface complexation model).
- pH: you can either specify a fixed pH or have the program calculate the pH for you.
- Input: you can edit input interactively (screenshot) or read from an input file.
- Output: You can view output on your screen (screenshot; updated September 2016), save in an output file, or export to an .CSV or .XML file (both types can be read by spreadsheet programs like EXCEL 2002 and later).
