Cloud point extraction in flow-based systems
Cloud point extraction is a green alternative for separation and preconcentration, whose advantages are magnified by coupling with flow analysis. This results in fast extractions, with improved precision and lower reagent consumption and waste generation.

Cloud point extraction coupled with back extraction: a green methodology in analytical chemistry. [PDF]
Recently, cloud point extraction (CPE) coupled with back extraction (BE) has been suggested as a promising alternative to liquid-liquid extraction. In CPE, non-ionic surfactants in aqueous solutions form micelles and the solution becomes turbid when heated to the cloud point temperature.

Cloud Point Extraction of α-Amino Acids [PDF]
Cloud point extraction with a polyethoxylated alcohol (Oxo-C10E4) is used to separate five α-amino acids: alanine, valine, leucine, isoleucine, and phenylalanine (0.75 wt.% in water), and their extraction efficiencies are compared. The variables affecting phase separation and extraction (wt.% surfactant and equilibrium temperature) are optimized using ...

Cloud Point Extraction for Electroanalysis: Anodic Stripping Voltammetry of Cadmium. [PDF]
Cloud point extraction (CPE) is a well-established technique for the preconcentration of hydrophobic species from water without the use of organic solvents. Subsequent analysis is then typically performed via atomic absorption spectroscopy (AAS), UV-vis spectroscopy, or high performance liquid chromatography (HPLC).
