DLLME employs a mixture of a high-density solvent(extractant) and water miscible polar solvent(disperser). Acetone, methanol, and ACN can be used as disperser,where as chlorinated solvents(e.g.,chlorobenzene,carbontetrachloride,and tetrachloroethylene)are useful as extractant. When mixture of extraction and dispersive solvents is added rapidly into anaqueous sample,a cloudy state, consisting off inedroplets of the extractant dispersed into the aqueous matrix,is formed.
