In this work, an adsorbent was prepared based on the attachment of organophosphorus acid extractants, namely, D2EHPA, CYANEX 272, and CYANEX 301, to the surface of superparamagnetic magnetite (Fe3O4) nanoparticles. The synthesized nanoparticles were coated with oleic acid, first by a chemisorption mechanism and later by the respective extractant via physical adsorption. The obtained core-shell ...

In this research, the kinetics of Co(II) extraction from sulfate medium by system “[C8H17NH3][Cyanex 272]+diluent sulfonated kerosene” were investigated using single drop falling technique. The time formation and coalescence was determined for calculating transfer flux. influences aqueous pH, concentration [C8H17NH3][Cyanex 272] on revised Co(II)-transfer flux (F') with aim obtaining reaction o...

Municipal Solid Waste Incineration (MSWI) fly ash contains significant amounts of leachable metals, and is therefore considered as hazardous waste. The increased amounts of fly ash generated cause environmental issues, management costs and accumulation of valuable metals in landfills. All these factors contribute to an increased interest in recognizing the ash as an urban mining target of metal...

Solvent extraction studies of copper and zinc have been carried out using Versatic 10 acid and Cyanex 272 separately from a model brass pickle liquor. Various parameters for the extraction and separation of copper and zinc such as effect of pH, extractant concentration, phase ratio etc. have been optimized. It was observed that copper was almost completely extracted into the organic phase compr...

We investigated the preparation of CMB (cobalt-manganese-bromide) and CMA (cobaltmanganese-acetate) liquid catalysts as petroleum liquid catalysts by simultaneously recovering Co and Mn from spent Li-ion battery cathode material. To prepare the liquid catalysts, the total preparation process for the liquid catalysts consisted of physical pre-treatments, such as grinding and sieving, and chemica...

La recuperación del ion de Litio se ha vuelto una búsqueda constante debido al incremento demanda baterías recargables. El objetivo este trabajo fue evaluar los extractantes; Cyanex 272 y 936P para determinar el extractante con mayor afinidad Li. Se analizó la eficiencia extracción ambos extractantes utilizando licores lixiviación sintéticas que contenían Li, K Al, donde evaluó pH porcentaje co...

Indium separation using ion exchange resins from acidic polymetallic and very diluted solutions are investigated. Since the selectivity of commercial have proven to be too low for an effective with high content other metals, Lewatit® TP 208 was impregnated common extractants enhance its properties. By resin impregnation D2EHPA Cyanex 272, not only selective indium recovery reached but also capa...

The performance requirements of modern lithium-ion batteries (LIBs) necessitate the use a number scarce and strategically sensitive metals such as lithium cobalt. Recycling end-of-life LIBs reduces demand on primary sources these helps reduce environmental impact LIB waste. Citric acid has proven to be an effective environmentally friendly sustainable lixiviant; however, formation metal citrate...
