• COMPARATIVE STUDY OF THE APPLICATION OF CHELATING RESINS FOR RARE EARTH RECOVERY Michael J. Page* and Karin Soldenhoff Mark D. Ogden Dept. Chemical and Biological Engineering, University of Sheffield ABSTRACT The adsorption properties of chelating ion exchange resins containing mixed sulfonic/phosphonic (SP), aminophosphonic (AP) or iminodiacetic (IDA) acid functional groups were investigated towards the rare earth elements

  • Applications of chelating resin for heavy metal removal from wastewater Jun Jiang , Xiao-Shuang Ma , Ling-Yun Xu , Li-Hua Wang , Gao-Yan Liu , Qing-Feng Xu  , Jian-Mei Lu  and Yong Zhang From the journal e-Polymers https://doi.org/10.1515/epoly-2014-0192 cite: https://www.degruyter.com/document/doi/10.1515/epoly-2014-0192/html Abstract The chelating resin was synthesized by free-radical copolymerization of iminodiacetic acid modified glycidyl methacrylate with a cross-linker N,N′-methylene biscarylamide at 70°C for removal of heavy metal ions from aqueous solutions.

  •  How Chelating Resins Behave? B By Peter S. Meyers CITE: The Surface Technology Environmental Resource Center Chelating resins are gaining acceptance as the best available technology for the removal of transition and heavy metal cations from ground water and from plating rinse waters. These specialty ion exchange resins are capable of removing metals selectively in the presence of other ions such as calcium, magnesium and

Benedetto Abstract - Indium can be recovered by treating residues, flue dusts, slags, and metallic intermediates in zinc smelting. This paper investigates the adsorption characteristics of indium and iron on an
