Subcritical water extraction of essential oils from Thymbra spicata
Food Chemistry, 2003 Essential oils from the leaves of Thymbra spicata L. were extracted using subcritical water. The extraction efficiencies of different temperatures (100, 125, 150 and 175°C), pressures (20, 60, and 90 bar) and flow rates (1, 2, and 3 ml min-1) were ...

Extraction of Tricyclazole from Soil and Sediment with Subcritical Water
Journal of Agricultural and Food Chemistry, 2000The use of subcritical water to extract tricyclazole from soils and sediments was examined. Extraction efficiency and kinetics were determined as a function of temperature, sample age, sample matrix, sample size, and flow rate. Extraction temperature was the most influential experimental factor affecting extraction efficiency and kinetics, with ...

Demetalisation of soils by continuous acidified subcritical water extraction
Talanta, 2002Acidified subcritical water is proposed for the continuous extraction of metals (namely, lead, copper, cadmium, arsenic, selenium and mercury) from soils prior to: (a) continuous derivatisation (by hydride formation for As and Se, and cold vapour formation for Hg) and determination by atomic fluorescence; and (b) determination by Graphite Furnace ...

Remediation of soil contaminated with dioxins by subcritical water extraction
Chemosphere, 2004The effectiveness of subcritical water extraction (SCWE) was examined for removing dioxins from contaminated soil. Most dioxins in the soil sample were reduced at 300 degrees C or more, but decreased dioxin concentrations were also observed at 150 degrees C.
