Cloud Point Extraction of α-Amino Acids [PDF]
Separation Science and Technology, 2014 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 of Δ9-tetrahydrocannabinol from cannabis resin [PDF]
Analytical and Bioanalytical Chemistry, 2013 A cloud point extraction coupled with high performance liquid chromatography (HPLC/UV) method was developed for the determination of Δ(9)-tetrahydrocannabinol (THC) in micellar phase. The nonionic surfactant "Dowfax 20B102" was used to extract and pre-concentrate THC from cannabis resin, prior to its determination with a HPLC-UV system (diode array ...
