Pressurized hot water extraction (PHWE).
Pressurized hot water extraction (PHWE) has become a popular green extraction method for different classes of compounds present in numerous kinds of matrices such as environmental, food and botanical samples. PHWE is also used in sample preparation to extract organic contaminants from foodstuff for food safety analysis and soils/sediments for environmental monitoring purposes. The main paramete...
متن کاملOn-line Combinations of Pressurized Hot-Water Extraction and Microporous Membrane Liquid–Liquid Extraction with Chromatography
298 Introduction Environmental and biological analyses are especially challenging for the analyst because sample matrices tend to be very complex and the analytes are present at very low levels. Selective and sensitive methods are needed for both sample preparation and analysis. Typically, extraction and clean-up are needed in the sample preparation, and the analyses are performed by chromatogr...
متن کاملPressurized hot ethanol extraction of carotenoids from carrot by-products.
Carotenoids are known for their antioxidant activity and health promoting effects. One of the richest sources of carotenoids are carrots. However, about 25% of the annual production is regarded as by-products due to strict market policies. The aim of this study was to extract carotenoids from those by-products. Conventional carotenoid extraction methods require the use of organic solvents, whic...
متن کاملSynthesize of Ion Imprinted Polymer for Selective Extraction of lead (II) from Environmental Water Samples
A new Pb(II) imprinted mercapto functionalized Montmorillonite was synthesize by an easy one step reaction by combining a surface imprinting technique for selective phase extraction of Pb(II) prior to its determinations by flame atomic absorption spectroscopy. The modified sorbent was characterized by FTIR and studied for preconcentration and determination of Pb(II) in natural water samples. Th...
متن کاملEvaluation of pressurized liquid extraction and pressurized hot water extraction for tanshinone I and IIA in Salvia miltiorrhiza using LC and LC-ESI-MS.
Pressurized liquid extraction (PLE) and pressurized hot water extraction (PHWE) using a laboratory-made system are applied for the extraction of thermally labile components such as tanshinone I and IIA in Salvia miltiorrhiza. PLE and PHWE are carried out dynamically at a flow of 1 mL/min, temperature between 95-140 degrees C, applied pressure of 10-20 bars, and extraction times of 20 and 40 min...
