Aug 21, 2024 · To achieve the deep separation of the acid leaching solution containing tungsten and molybdenum, it was crucial to depolymerise the tungsten and molybdenum polymerisation ions and enhance the differences in their properties. Extraction and adsorption methods were used in combination for the separation of tungsten and molybdenum process.

Feb 1, 2022 · The synergistic mechanism of TBP for Mo and W extraction was revealed through Raman, FT-IR and 31 P NMR spectroscopy, proposing a synergistic extraction compound TBP·[H 2 Mo 2 O 3 (O 2) 4 ·2H 2 O]·TRPO. The experimental results showed that keeping a higher equilibrium pH (2–2.5) can improve the separation efficiency of W and Mo, which ...

Oct 1, 2012 · A novel process of solvent extraction for separation of molybdenum (Mo) from ammonium tungstate (W) solution containing high content of Mo was developed using a mixture of tri-alkyl phosphine oxide (TRPO) and tributyl phosphate (TBP) as extractant and hydrogen peroxide (H 2 O 2) as complex agent.

HDEHP diluted with CCl4 (without TBP), Mo occurs in the form of molybdenyl (absorption bands at 918 and 958 cm–1). The spectrum of Mo in HDBP diluted with xylene has a similar shape [6].

Feb 2, 2022 · In this work, selective separation of molybdenum was comprehensively investigated by tributyl phosphate (TBP) with the emphasis on the hydrochloric acid concentration, TBP concentration, reaction time, and oil–water ratio. The results indicated that molybdenum was effectively extracted by 40% (v/v) TBP.

Dec 1, 2020 · The mixture of TBP and P507 showed a strong synergistic effect on Mo, and the extraction efficiency of Mo increased substantially compared to only TBP or P507. With increasing volume fraction of P507, the extraction efficiency reached a maximum of 97% at X P507 = 0.5 and, subsequently, gradually decreased.

Jan 10, 2022 · The separation of molybdenum from peroxotungstate solution with neutral phosphorus extractant such as trialkyl phosphine oxide (TRPO), tri-butyl phosphate (TBP) is often accompanied by extraction...

Tributyl phosphate, known commonly as TBP, is an organophosphorus compound with the chemical formula (CH 3 CH 2 CH 2 CH 2 O) 3 PO. This colourless, odorless liquid finds some applications as an extractant and a plasticizer. It is an ester of phosphoric acid with n-butanol.
