| Abstract: |
| Separation of antimony and selenium from arsenic alkali residues was investigated. Insoluble selenite was changed into soluble selenate using hydrogen peroxide as oxidant. The results show that its kinetics is unreacted-core shrinking model which has no solid products generated. Its kinetics equation is . The reaction activation energy is -15.490 6 kJ/mol, and it is a chemical reaction-controlled process. |
