Ultrasonic removal of heavy metals from waste oils

Electrochemical Applications of Power Ultrasound

“…Jagner et al have used a stripping potentiometric method after pre-treatment [73], and even polarography has been used following an ICl (iodine monochloride) pre-treatment [74]. Lead can be detected more simply using biphasic sono-ASV, and has been reported using a Hg/Pt electrode in an emulsion of the petrol sample with [68].…”

Ultrasonically Enhanced Voltammetric Analysis and Applications: An Overview

“…Furthermore, Jagner et al [145] used stripping potentiometry with sample pretreatment to dilute the petroleum sample. Polarography after treatment with iodine monochloride has been investigated whilst the extraction of lead and other heavy metals from waste oils using ultrasonic and acid digestion techniques has been reported [146].…”

Removal of Heavy Metal from Wastewater

“…For example, usual physical pathways like ion exchange, activated carbon, and membrane adsorption belong to the latter costly group, especially when treating large amounts of wastewater [14]. In recent years, using ultrasonic technology to control and remove heavy metals has gained some attention [15][16][17][18][19][20][21][22][23]. Further, the combined effects of ultrasound with adsorbent materials show higher removal capacity.…”
