Selective radionuclide and heavy metal sorption using functionalised magnetic nanoparticles for environmental remediation

Abstract

In this paper the removal of a wide range of heavy metal ions from different chemical environments has been explored with the use of phosphate-functionalised superparamagnetic iron oxide nanoparticles (SPIONs), specifically magnetite (Fe3O4).

Synthesis of Boronate Affinity-Based Oriented Dummy Template-Imprinted Magnetic Nanomaterials for Rapid and Efficient Solid-Phase Extraction of Ellagic Acid from Food

“…Magnetic Fe 3 O 4 nanoparticles (MNPs) [ 41 , 42 , 43 ], due to their low cost, magnetic susceptibility, low toxicity, and good biocompatibility, can be used as supporting materials. In the past few years, various types of functionalized MNPs such as imprinted MNPs, metal-chelated MNPs, and other functional MNPs have been widely used in diverse fields such as solid-phase extraction, biomedicine, environmental applications, and wastewater treatment [ 41 , 44 , 45 , 46 , 47 , 48 ]. Therefore, boronic acid-functionalized MNPs can effectively serve as a solid substrate for immobilizing and eliminating GA.…”

Boronate affinity-based clindamycin-imprinted magnetic nanomaterials for rapid, efficient and selective extraction and determination of clindamycin in animal-derived food

“…In recent years, magnetic nanoparticles (MNPs) such as imprinted MNPs, metal-chelated MNPs and other functional MNPs have widespread applications in different areas including protein purification, solid-phase extraction, energy, biomedicine, environmental fields, bioimaging, waste water treatment, and immobilisation of cells and enzymes. 48–58 Thus, boronic acid-functionalized MNPs can be well used as a solid substrate for the immobilization and removal of CLN. In addition, the imprinting coating is the key to the binding properties of imprinted materials.…”

Advancements in Biomonitoring and Remediation Treatments of Pollutants in Aquatic Environments, 2nd Edition

“…Nanotechnologies represent a deeply studied and applied solution for removing heavy metals, organic pollutants, and microorganisms with the enhanced adsorption and degradation capacity of pollutants via redox reactions [52][53][54][55]. These techniques can also employ different solutions, such as metal-organic framework materials [56] or magnetic nanoparticles [57,58]. The zero-valent iron nanoparticles, simple or modified, demonstrate very high efficiency in removing both organic and inorganic pollutants [59].…”
