Recovery of dissolved substances in liquid-liquid extraction- The recovery of solutes in liquid-liquid extraction is the fraction of solutes recovered in the liquid-liquid extraction process.
Mass fraction of solute in raffinate- The mass fraction of solute in the raffinate phase is the mass fraction of solute in the raffinate phase after separation of the ternary mixture.
Flow rate of the raffinate phase in LLE-(measured in moles per second)- The flow rate of the raffinate phase in LLE is the flow rate of the raffinate phase after separation in the liquid-liquid extraction process.
Mass fraction of solute in feed- Mass fraction of solute in the feed is the mass fraction of solute in the feed to the liquid-liquid extraction process.
Feed flow in liquid-liquid extraction-(measured in moles per second)- The liquid-liquid extraction feed flow rate is the flow rate of the feed to the liquid-liquid extraction process for separation.

STEP 1: Convert input(s) to base unit

Mass fraction of solute in raffinate:0.35 --> No conversion required
Raffinate phase flow in LLE:40 moles per second -> 40 moles per second No conversion needed
Mass fraction of the solute in the feed:0.5 --> No conversion required
Feed flow in liquid-liquid extraction:100 moles per second -> 100 moles per second No conversion required

STEP 2: Evaluate formula

Replace input values ​​in formula

Rsolved= 1-((xC*R)/(zC*F)) -->1-((0,35*40)/(0,5*100))

Evaluate ... ...

Rsolved= 0,72

## What is liquid-liquid extraction?

Liquid-Liquid Extraction (LLE), also known as solvent extraction, is a method of separating compounds or metal complexes based on their relative solubilities in two different, immiscible liquids, usually water (polar) and an organic solvent (non-polar) . There is a net transfer of one or more species from one liquid to another liquid phase, generally from aqueous to organic. The transfer is driven by the chemical potential, i. H. once the transfer is complete, the overall system of chemical components that make up the solutes and the solvents are in a more stable configuration (lower free energy). The solvent enriched with solutes is called the extract. The feed solution, which is depleted in solutes, is referred to as the raffinate.
