摘 要:鈷鎳的化學性質(zhì)非常相似,在礦床中常共生、伴生,因此在各種含鈷廢渣中常有鎳,如鎳冶煉轉(zhuǎn)爐渣、銅冶煉含鈷轉(zhuǎn)爐渣、鎳精煉含鈷渣等,在各種特殊合金材料、電池材料、催化劑中,也都同時含有鈷鎳。本文綜述了目前分離鎳鈷的常用方法；對液膜提取過程的研究現(xiàn)狀和意義進行了闡述；建立了皂化P507微乳液膜分離鈷鎳的新方法；研究了以P507為載體，航空煤油為溶劑的微乳液膜體系分離鎳鈷的分離性能。考察了萃原液的初始濃度、P507的體積濃度、pH值、乳水比和萃取時間五個因素對分離性能的影響，從而確定了合適的萃取條件為：萃原液初始濃度為0.5mol/L；萃原液pH為2.0；相比 V(o):V(a)為 2:1時 ；單級萃取10 min；10 %P507和90 %磺化煤油的皂化微乳液為萃取劑。 關(guān)鍵詞：鈷鎳；微乳液膜；最優(yōu)條件
Abstract : Cobalt nickel chemical properties are very similar, in deposits, so often symbiosis and associated in various containing cobalt residues, such as nickel has a tendency to nickel copper smelting blast furnace slag, smelting turn containing cobalt turn slag, nickel refining cobaltiferous slag etc, in various special alloy material, battery materials, catalyst, are also contains cobalt and nickel. This paper reviews the current methods of separation of nickel and cobalt; of liquid membrane extraction process, the research present situation and meaning is described; Established saponification P507 microemulsion membrane separation, a new method of nickel and cobalt; Researches on the P507 as the carrier, kerosene as solvent separation membrane system of microemulsion nickel and cobalt separation properties. The P507 examined the initial concentration of the water, breast, pH value than, extraction time and extraction phase ions concentration of separation factors such as the influence of performance, so as to determine the appropriate extraction conditions for: compared to 2.0, bioburden pH V(o):V(a) for 2:1, single stage extraction 10 min, gathers the initial concentration of the stock for 0.5 mol / L, 10% P507 and 90% sulphonated kerosene saponification microemulsion for extracting agent. Keywords: Cobalt Nickel； Microemulsion film；Optimal conditions |
