When a mixture of the extraction and disperser solvents is rapidly injected into the aqueous sample, a "cloudy solution" is formed. This cloudiness is caused by the formation of millions of fine droplets of the extraction solvent dispersed throughout the sample. This creates an enormous surface area, allowing for nearly instantaneous mass transfer and equilibrium of the analytes from the aqueous phase into the organic droplets. A standard DLLME procedure typically follows these stages:

The settled organic phase is collected using a microsyringe and injected into an analytical instrument for quantification. Key Advantages When a mixture of the extraction and disperser

is a powerful and versatile sample preparation technique used in analytical chemistry to concentrate and extract trace levels of organic and inorganic analytes from various matrices. Since its introduction in 2006 by Rezaee and colleagues, DLLME has gained global popularity for its simplicity, speed, and minimal use of organic solvents, aligning with the principles of green chemistry. The Fundamental Principles of DLLME A standard DLLME procedure typically follows these stages:

DLLME offers several distinct benefits over traditional extraction methods like Liquid-Liquid Extraction (LLE) or Solid-Phase Extraction (SPE): The Fundamental Principles of DLLME DLLME offers several

The core of DLLME is a ternary solvent system consisting of:

A water-miscible organic solvent (e.g., methanol, acetonitrile, or acetone) that is also soluble in the extraction solvent.

Typically an aqueous sample containing the target analytes.
