Membrane extraction

  "id": "MLC-T-CHM-007158",
  "term": "Membrane extraction",
  "field": "Chemistry",
  "definition": "A separation process where a semipermeable membrane acts as a selective barrier between two phases, allowing specific components of a mixture to pass through it. The driving force for transport across the membrane may be a concentration gradient, pressure difference, or electrical potential. This technique is distinct from filtration, as it involves selective permeation at a molecular level rather than physical retention of particles.",
