Recovery of metals from waste nickel-metal hydride batteries using multifunctional Diphonix resin

Abstract

In this study, Diphonix resin containing sulfonic, diphosphonic and carboxylic groups was used to evaluate the adsorption capacity of metal ions contained in the nickel-metal hydride batteries (Ni-MH). This type of ion exchanger can be considered as the multifunctional material having great affinity to many metal ions. Using Diphonix resin adsorption process was carried out for La(III) and Ni(II) ions to characterize kinetic, adsorption and thermodynamic parameters. Preliminary studies of the Nd(III), Ce(III), La(III), Fe(III), Co(II), Ni(II), Cu(II) and Zn(II) metal ions mixture were also performed. The best results of adsorption studies were obtained using 0.2 M HNO 3. Diphonix resin exhibits especially good adsorptive properties with respect to rare earth element ions (adsorption efficiency of about 100%) in comparison with the heavy metal ions in the second oxidation state (about 50% or below). The series of affinity of the resin for the studied ions can be presented as follows: La(III) > Fe(III) > Nd(III) > Ce(III) > Cu(II) > Zn(II) > Co(II) > Ni(II). The obtained results confirmed the possibility of further use of the resin for the recovery and separation of rare earth elements from solutions after Ni-MH batteries leaching.

Functionalization of polymers and nanomaterials for water treatment, food packaging, textile and biomedical applications: a review

“…Likewise, compared to common resin, the bifunctional chelating resin bearing phosphonic and sulfonic groups showed better removal of fluoride (Li et al 2020). Among all examples, bifunctional polymer-supported aminophosphonic acid (Zidan et al 2020), carboxylic-amine-phosphonic acid (Wang et al 2020a), diphosphonic (Fila et al 2019), polyamine in the presence of HDPE (Zhao et al 2019a) proved to be of interest for the removal of metal cations.…”

Efficient Recovery of Rare Earth Elements (Pr(III) and Tm(III)) From Mining Residues Using a New Phosphorylated Hydrogel (Algal Biomass/PEI)

“…Sorbents have been designed by the functionalization of clays for the recovery of REEs [19] and the preparation of composites based on silica [20][21][22][23] or carbon-based supports [21,24,25]. Synthetic resins have been functionalized with phosphorus groups [26][27][28][29][30][31], taking advantage of the affinity of phosphonic-based reactive groups for REEs.…”

Magnetic/Polyetherimide-Acrylonitrile Composite Nanofibers for Nickel Ion Removal from Aqueous Solution

“…Nickel ions ( ) are a common environmental toxicant that are widely produced by various industries and products, such as lead framing, electroplating, tableware, plastics manufacturing, fertilizers, nickel-based batteries, pigments, metal finishing, connecters, mining, and metallurgical operations. Nickel is a carcinogen because its ingestion in high concentrations can create numerous health problems, such as kidney damage and lung and stomach problems (e.g., vomiting, diarrhea, renal edema, skin dermatitis, nausea, and pulmonary fibrosis) [ 1 , 2 , 3 ].…”
