Iron determination by FAAS in fish feed and feces after ultrasound-assisted extraction
This paper proposes a method to determine iron in samples of fish feed and feces using ultrasound in the extraction of the analyte and in subsequent quantification by flame atomic absorption spectrometry. Using HCl 0.10 ...
FAAS determination of metal nutrients in fish feed after ultrasound extraction
(Elsevier B.V., 2009-03-15)
This paper proposes a method to determine calcium, magnesium, manganese and zinc in fish feed samples using ultrasound in the analyte extraction process, and subsequent quantification by flame atomic absorption spectrometry ...
Ultrasound-assisted extraction of Na and K from swine feed and its application in a digestibility assay: A green analytical procedure
The study is aimed to evaluate the efficiency of ultrasound-assisted extraction (UAE) as a simple strategy focused on sample preparation for metal determination in biological samples. The extraction of sodium and potassium ...
The Effects Of Amplitudes Ultrasound-assisted Solvent Extraction And Pretreatment Time On The Yield And Quality Of Pistacia Khinjuk Hull Oil
(Japan Oil Chemists SocTokyo, 2016)
Comparison between conventional and ultrasound-assisted techniques for extraction of anthocyanins from grape pomace. Experimental results and mathematical modeling
Conventional and ultrasound assisted extraction of anthocyanins from grape pomace are here analyzed and compared. Mathematical modeling is used firstly to represent the extraction process and determine the associated mass ...
Ultrasound-assisted pressurized solvent extraction for aliphatic and polycyclic aromatic hydrocarbons from soils
In the present work the efficiency of extraction of aliphatic diesel range organics (DROs) and polycyclic aromatic hydrocarbons (PAHs) from soil was assessed by using dynamic modes of pressurized solvent extraction (PSE), ...
