Novel Method for Stripping of Molybdenum (VI) after its Extraction with Cyanex 301
Hydrofluoric acid has been used as a novel stripping agent for molybdenum (VI) after its extraction with Cyanex 301. In the extraction steps effects of parameters such as type and initial concentration of acid, type of diluent, extractant concentration, metal concentration and temperature have been studied. In thestripping step, the effects of various stripping agents on stripping efficiency ha...
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 کاملRecovery 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 کاملSYNERGISTIC SOLVENT EXTRACTION OF Co(II) AND Li(I) FROM AQUEOUS CHLORIDE SOLUTIONS WITH MIXTURE OF CYANEX 272 AND TBP
In this work, separation of cobalt(II) over lithium(I) ions from aqueous chloride solutions by synergistic solvent extraction (SX) has been studied. A synergistic mixture of commercial extractants such as bis(2,4,4-trimethylpentyl)phosphinic acid (Cyanex 272) and tributyl phosphate (TBP) in kerosene was used as a selective extractant. The investigations were first performed to select optimal co...
متن کاملExtraction of Silver Ions from Aqueous Solutions by Emulsion Liquid Membrane
A comprehensive study pertaining to the emulsion liquid membrane (ELM) extraction process to enrich dilute aqueous solutions of silver salt is presented. The study has highlighted the importance and influence of membrane composition for maximizing the extraction of Ag+ ions. The liquid membrane was made up of Cyanex-302 as an extractant and the industrial solvent mainly consists of p...
