  • During solvent extraction, if the solute is found to be less soluble in organic phase, then continuous extraction method is employed.
  • In this method, the same amount of organic solvent is used repeatedly for extraction.
  • This ensures that the most of the solute gets extracted in the organic phase.
  • This technique involves continuous distillation of the solvent within the same assembly. Hence, the use of large quantity of organic solvent is avoided.
