  • 摘要: 利用共沉淀法将锂电池废液中的有价金属(Me:Co、Ni、Mn)固定在铁氧体晶格中,得到一种掺杂钴镍锰的铁氧体,不仅可以去除废液中的金属污染物,还可作为理想的臭氧氧化催化剂。研究表明,在T=90 ℃,Fe/Me(摩尔比)=20的条件下,掺杂钴、镍的铁氧体最佳pH为9,掺杂锰的铁氧体最佳pH为11。进一步分析了在不同pH条件下,铁氧体形成α-Fe2O3、γ-Fe2O3、Fe3O4 3种晶型的原因并探讨钴镍锰掺杂的铁氧体对臭氧催化降解苯酚效率的影响。
    Abstract: The coprecipitation process was involved in fixing valuable metals Co/Ni/Mn from the spent lithium ion batteries (LIBs) wastewater into ferrites crystal lattice, obtaining a Co/Ni/Mn doped ferrite which not only realize the goal of removing valuable metals from LIBs wastewater but also could be a distinguished ozone oxidation catalyst. The results showed that when the molar ratio of Fe/valuable metals was 20 and temperature of solutions reached at 90 ℃, the optimum pH of Co/Ni doped ferrites was 9 while the optimum pH of Mn doped ferrites was 11. Moreover, the formations of α-Fe2O3, γ-Fe2O3, Fe3O4 in different pH conditions were discussed and the reasons of a higher catalytic degradation speed after adding valuable metals doped ferrites were analyzed.
