Economic analysis of ,supercritical, fluid ,extraction, (SFE) processes have to be evaluated for future commercial applications. Capital costs are usually not linear with increasing pressure of ,extraction,, and although operation costs and regulations are generally less expensive and regulated than handling flammable organic solvents, continuous, batch, or semicontinuous approaches have to …

Sonication, microwave-assisted ,extraction, (MAE) and ,supercritical, fluid (SFE) ,extraction, have all been successfully employed to recover PCBs and OCPs from solid samples (Table 1). Soxhlet is regarded as more reliable than sonication, SFE, or shake flask-type methods and equivalent to (but not as rapid as) MAE and PLE for a wide range of environmental matrices [ 25 ].

A method for separating a desired metal or metalloi from impurities using a ,supercritical extraction, process based on solubility differences between the components, as well as the ability to vary the solvent power of the ,supercritical, fluid, is described. The use of adduct-forming agents, such as phosphorous-containing ligands, to separate metal or metalloid chelates in such …

An alternative to these types of ,extraction techniques, is ,supercritical, fluid ,extraction, (SFE). SFE offers a relatively rapid, simple and inexpensive technique to perform sample preparations. The basis of SFE is that a fluid, such as carbon dioxide, is held at a specific pressure, temperature and flowrate, which is above its critical temperature and pressure and thus is a ,supercritical, fluid.

1/1/1997, · In SFE, a ,supercritical, fluid is used as the ,extraction, solvent instead of the typical liquids encountered in the laboratory currently—for example, methylene chloride, hexane, and methanol. The sample to be extracted is exposed to the ,supercritical, solvent that dissolves and removes some subset of extractables from a raw sample.

The ,extraction, efficiency was evaluated by estimation of carotenoid yield determined spectrophotometrically. Classical ,extraction, using hexane (18.27 mg β-carotene/100 g DM) was the most efficient method for isolation of carotenoids, compared to ethyl acetate classical ,extraction, (15.73 mg β-carotene/100 g DM) and ,supercritical, CO₂ ,extraction, (0.19 mg β-carotene/100 g DM).
