Working examples from the PhreeqPython notebooks, as live editors in the browser. Click Run (or Ctrl+Enter) on each cell, or Run all to execute every editor on the page in order. Editors on a page share a session.

The original Jupyter notebooks remain in examples/ if you prefer to run them locally.

General¶

• Functionality overview — create solutions, query properties, mix, copy
• Carbonic acid equilibrium — CO₂ / HCO₃⁻ / CO₃²⁻ vs pH

Equilibrium¶

• Ca–F and fluorite — fluoride vs calcium during feldspar dissolution
• Calcite dissolution — calcite vs CO₂ pressure, including mixing
• Gibbsite solubility — dissolved Al vs pH
• Aluminium drinking-water limit — pH where 0.2 mg/kgw Al is in equilibrium with gibbsite
• Gypsum on evaporation — gypsum precipitation as water is removed

Kinetics¶

• Quartz dissolution — solution.kinetics() and SciPy odeint
• Monod kinetics — methanogenic phenol biodegradation

Gas¶

• Solubilities — O₂, N₂, CH₄, and CO₂ in 4 M NaCl
• Gas-phase calculations — fixed-pressure vs fixed-volume gas after organic-matter reaction
