Ultrasound-assisted extraction of organic contaminants

TrAC - Trends in Analytical Chemistry, 2019
Abstract Ultrasound-assisted extraction is an efficient environmental friendly technique, since the solvent volume required in sample preparation is reduced and the extraction time is shortened in comparison to classical extraction procedures. Ultrasound radiation has been primarily applied to the extraction of analytes from solid samples.

Ultrasound-assisted extraction and in situ derivatization

Journal of Chromatography A, 2013
Ultrasound (US) is a type of energy of growing interest for analytical chemists. The favorable effect of US on mass transfer between two phases in the same or different state has been widely demonstrated as did the number of chemical reactions accelerated/improved under ultrasonic influence.

MICROWAVE AND ULTRASOUND ASSISTED EXTRACTION OF SOYBEAN OIL

Transactions of the ASAE, 2004
The effect of ultrasound and microwave assistance in enhancing extraction oil yields from soybeans when different solvents are used for extraction was investigated in two separate experiments. Each study involved a three-factor factorial following a completely randomized design that was replicated three times.
