Asymmetric membrane containing ionic liquid [A336] [P507] for the preconcentration and separation of heavy rare earth lutetium

Chen, Li, Chen, Ji·2016·ACS Sustainable Chemistry & Engineering

Abstract

A novel polymer inclusion membrane (PIM) was prepared for the preconcentration and separation of heavy rare earth element (HREE) Lutetium (Lu) from dilute solution. The membrane was composed of poly(vinylidene fluoride) (PVDF) as a matrix and bifunctional ionic liquid extractant [tricaprylmethylammonium][di(2-ethylhexyl)orthophosphinate] ([A336][P507]) as carrier, without any plasticizer. A weak physical effect existed between PVDF chain segment and [A336][P507], but no chemical interaction. Structure characterization and transport experiment both proved the membrane to be an asymmetric structure and LuCl 3 would transport faster from surface with small pores to large pores. YbCl 3 was transported much faster than LuCl 3 which was different in liquid–liquid extraction. Preconcentration experiment realized a great acceleration on the transport of LuCl 3 . And the PIM was proved stable and durable. All these would provide a novel approach to the preconcentration and separation of Lu from dilute solution like leachate of southern ion adsorbed rare earth deposit.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
