Deleterious effect of ammonium extraction from soil assisted by ultrasound
(Elsevier, 2004)
Ultrasound has been used to assist extraction procedures from solid samples based on the decrease of gradient concentration in the vicinity
of particulate matter and the microjet produced during cavitation. In the present ...
Iron determination by FAAS in fish feed and feces after ultrasound-assisted extraction
(2009-01-01)
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 ...
