Respuesta :

In solvent extraction, we use two solvents. The important characteristic of extracting solvent is it should be immiscible with the second solvent.

What is solvent extraction and why is it important?

  • Solvent extraction also called liquid-liquid extraction (LLE) and partitioning, is a method to separate compounds based on their relative solubilities in two different immiscible liquids.
  • The main purpose of solvent extraction is to isolate hazardous materials from the sediments and sludge or separate the useful components from debris.

What are immiscible liquids?

Immiscible liquids are those which won't mix to give a single phase.

Oil and water are examples of immiscible liquids.

Thus, in liquid-liquid extraction, the two solvents should be immiscible with each other.
