Recovery of cobalt sulfate from spent lithium ion batteries by reductive leaching and solvent extraction with Cyanex-272
Cobalt sulfate was recovered from crushed and screened prismatic type spent lithium ion batteries (LIBs) containing 5~20 % Co, 5~7 % Li, 5~10 % Ni, 15% organic chemicals, and 7% plastics together with Cu, Al, Fe, and Mn. Cobalt was reductively leached from the -16 mesh fraction in 1 h by stirring with 2 M H2SO4 and 6 vol% H2O2, at 60 C and 300 rpm using a solid/liquid ratio of 100 g/L to give a...
متن کاملSeparation of Nickel and Zinc Ions in a Synthetic Acidic Solution by Solvent Extraction Using D2ehpa and Cyanex 272
Solvent extraction was used to recover nickel and zinc from synthetic acidic solution. Many leaching solution and waste waters contain both zinc and nickel at the same time. Bis (2,4,4trimethylpentyl) phosphinic acid (Cyanex 272) and Di(2-ethylhexyl) phosphoric acid (D2EHPA) were used to separate nickel and zinc. In the D2EHPA system, at equilibrium pH of 2, zinc extraction was more than 98% wh...
متن کاملPreparation of Amidoxime Polyacrylonitrile Chelating Nanofibers and Their Application for Adsorption of Metal Ions
Polyacrylonitrile (PAN) nanofibers were prepared by electrospinning and they were modified with hydroxylamine to synthesize amidoxime polyacrylonitrile (AOPAN) chelating nanofibers, which were applied to adsorb copper and iron ions. The conversion of the nitrile group in PAN was calculated by the gravimetric method. The structure and surface morphology of the AOPAN nanofiber were characterized ...
متن کاملPreparation and photoluminescence of yttrium hydroxide and yttrium oxide doped with europium nanowires
Single-crystalline Y(OH)3:Eu nanowires have been prepared by polymer-assisted hydrothermal method. The yields of the nanowires were higher than 95%. XRD patterns showed that the products were the hexagonal Y(OH)3 structure. SEM images displayed that the nanowires consisted of nanobelts and nanorods. The nanorods have the diameter of about 85 nm and length up to several tens of microns, and the ...
متن کاملTHESIS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY Hydrometallurgical Recovery of Rare Earth Elements from Fluorescent Lamp Waste Fractions
Recovery and reuse of materials is important for a circular economy. In recent years the recovery of critical metals from end-of-life products has received increased attention. Various streams, e.g. permanent magnets, nickel metal hydride batteries and fluorescent lamps are considered targets for the recovery of rare earth elements (REEs). The last can be a source of up to six different REEs: e...
