Mechanism Study on Selective Extraction of Nickel from Acidic Sulfate Solution by Using the Synergistic Solvent Extraction System of P204 and 4PC AITranslate
Abstract AITranslate
The mechanism of synergistic solvent extraction of nickel by P204 and 4PC from acidic sulfate solution was studied with slope method,constant molecale method and saturation extraction method,respectively. The thermodynamic equilibrium constant of the synergistic reaction was determined,and its enthalpy and entropy changes were also obtained.The results show that the combination of P204 with 4PC has a positive synergistic effect for nickel extraction,and the extracted complex is identified as NiA2L2.The synergistic solvent extraction is an endothermic reaction with enthalpy change of 29.52J/mol and entropy change of-6.53kJ/(mol·K).The synergistic solvent extraction system of P204and 4PC can obviously promote the selective extraction of nickel from acidic sulfate solution.
