How to use the solvent extraction efficiency calculator
Find how much solute stays in water after several extractions with fresh solvent. Enter distribution coefficient, aqueous volume, solvent volume per extraction, number of extractions in the fields above; the fraction of solute left in water, fraction extracted are computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “liquid liquid extraction efficiency”, “distribution coefficient”, “extraction left in water”, “calculate solvent extraction efficiency”, “find fraction of solute left in water”.
Formula
Variables
- D — Distribution coefficient
- Va — Aqueous volume (mL)
- Vo — Solvent volume per extraction (mL)
- n — Number of extractions
Worked example
With distribution coefficient = 5, aqueous volume = 100 mL, solvent volume per extraction = 50 mL, number of extractions = 2, the calculator gives fraction of solute left in water ≈ 8.163265 %; fraction extracted ≈ 91.83673 %.
Frequently asked questions
What is the solvent extraction efficiency calculator used for?
Find how much solute stays in water after several extractions with fresh solvent. It helps with questions such as “liquid liquid extraction efficiency”, “distribution coefficient”, “extraction left in water”.
What is the formula for the solvent extraction efficiency calculation?
Fraction of solute left in water (%) = 100 × (Va / (Va+D × Vo))^n. Fraction extracted (%) = 100-[Fraction of solute left in water]. Here D is distribution coefficient, Va is aqueous volume (mL), Vo is solvent volume per extraction (mL), n is number of extractions.
What inputs do I need for the solvent extraction efficiency calculator?
You need distribution coefficient, aqueous volume in mL, solvent volume per extraction in mL, number of extractions. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the solvent extraction efficiency calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the solvent extraction efficiency result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
