Title Recovery of Molybdenum from waste water by extraction with 18-crown ether-6 using DFT method Type Presentation Keywords Molybdenum, DFT, Crown ether, waste water, Extraction Abstract Crown ether complexes are the best compound and stable material. Molybdenum crown ether complexes was extracted theoretically by density functional theory from waste water in this study by b3lyp/lanl2dz basis set and considered it could be used in experimental process.
