Solvent Extraction Distribution
Compute equilibrium distribution and phase metal fraction with explicit phase volumes and matched concentration units; speciation is external.
Description
Distribution ratio compares equilibrium concentrations in organic and aqueous phases.
Distribution ratio compares equilibrium concentrations in organic and aqueous phases. Phase volumes convert that concentration ratio into a total metal partition.
The tool returns distributionRatio (distribution ratio); organicMetalFraction (organic metal fraction). Input measurements and model parameters are supplied by the caller; the tool computes the stated summary rather than acquiring those measurements.
When to use Solvent Extraction Distribution
Use Solvent Extraction Distribution when you already have organicEquilibriumConcentration, aqueousEquilibriumConcentration, organicVolumeLiters, aqueousVolumeLiters and want distributionRatio, organicMetalFraction. This is useful for checking a supplied calculation, documenting a measurement convention, or comparing observations prepared on the same basis.
How to use Solvent Extraction Distribution and understand its results
- Enter organicEquilibriumConcentration, aqueousEquilibriumConcentration, organicVolumeLiters, aqueousVolumeLiters using the field table below. Match the units, ordering and data boundaries described in the calculation.
- Run the tool after checking the stated bounds and matching paired observations or categories. A malformed request gives a tool error rather than a usable measurement.
- Read distributionRatio, organicMetalFraction. Use the calculation and interpretation below to distinguish amounts, ratios, signs and decision flags where applicable.
- Review the supplied parameters and assumptions before using the result in a report or comparing it with another observation.
| Input field | Meaning | Value type and bounds | Requirement |
|---|---|---|---|
| organicEquilibriumConcentration | Organic equilibrium concentration | number | Required |
| aqueousEquilibriumConcentration | Aqueous equilibrium concentration | number | Required |
| organicVolumeLiters | Organic volume liters | number | Required |
| aqueousVolumeLiters | Aqueous volume liters | number | Required |
Use nonnegative organic concentration, positive aqueous concentration and positive phase volumes with compatible concentration units.
D = Corganic/Caqueous; organic fraction = (D×Vorganic/Vaqueous)/(1+D×Vorganic/Vaqueous) The symbols refer to the supplied quantities or generated values described above; unit conversions and comparison boundaries follow the stated implementation.

}Limitations and assumptions
Equilibrium concentrations are supplied. No kinetics, loading dependence or chemical speciation is inferred.
Numerical inputs must be finite. The tool checks its declared input shape and calculation constraints; those checks do not verify the quality, calibration or representativeness of the supplied observations.
Alternative or Complementary methods
Solvent Extraction Stages: Count ideal crosscurrent stages with fresh solute-free organic at each stage and constant D/phase ratio; not countercurrent McCabe–Thiele construction. Overall Recovery: Propagate inventory through serial conditional recoveries and expose losses; parallel-stream recoveries must not be multiplied.
