| 中文摘要 | background: numerous high purity ammonium-type ionic liquid extractants have been prepared for engineering purposes. bifunctional ionic liquid extractants (bif-iles) have been widely applied to separate and extract rare earths and metal ions with high extraction efficiencies and selectivities. in the present study, new bif-iles [a336][p204] and [a336][p507] have been used to extract rare earths from a simulated solution of a fluorescent powder in a high concentration of al(no(3))(3). results: bif-iles were prepared from aliquat336 (a336) and the commercial organophosphorus acid extractants, p204 and p507. these extractants [a336][p204] and [a336][p507] have similar characteristics to neutral organophosphorus extractants. when these bif-iles were used to extract re(iii) from a simulated waste fluorescent powder system a third phase appeared which could be eliminated by the addition of 10% isopropanol modifier. the coexisting al(2)o(3) in the fluorescent powder was changed to a salting-out agent (al(no(3))(3)) in the extraction process and promoted the extraction efficiency of re(iii). using a countercurrent extraction process at a phase ratio v(o) : v(w) = 4 : 1 and ph = 0.56, the re(iii) recovery reached 95.2% in 5-7 stages. finally, the extractabilities of these bifunctional extractants were compared with the neutral organophosphorus extractants p350, tbp and cyanex923 at different concentrations, initial phs and temperatures. conclusions: by comparison with other neutral organophosphorus extractants, bif-iles [a336][p204] and [a336][p507] can be considered efficient potential extractants for separating and recycling rees and al(2)o(3) from waste fluorescent powder.
