| 其它 | abstract：The integrated hydrometallurgical approach routed through Microwave (MW) assisted leaching-cum-solvent extraction-precipitation for recovery of MoO3 from spent desulphurization catalyst was investigated. Selective separation of molybdenum (Mo) was obtained using the ionic liquid as Cyphos 104. In leaching study the role of MW power and H2SO4 concentration appears to be critical on transforming sulphide and oxide phase of metals (Mo, Al and Ni) in the spent catalyst phase into respective metal sulphate that led to have enhancement of metal leaching efficiency. At the optimum leaching condition: MW power of 1000Watt, 10(V/V)% H2SO4, 10(W/V)% (S/L) more than 99 % of Mo, 98 % of Al and 99 % of Ni was extracted with dilute acid. The leach liquor bearing 10.01 g/L of Mo, 27 g/L of Al and 2 g/L of Ni was subjected to Mo extraction using the ionic liquid(IL) of Cyphos 104. |
