Extraction of vanadium from direct acid leaching solution
2018-5-1 Vanadium existed in form of [H 2 V 10 O 28] 4− within a wide pH range of 1–3.5, but dissociation of (R 3 NH) 2 SO 4 occurred at pH > 2.0, which hampered the extraction. Moreover, Fe(III) was precipitated by hydrolysis at pH > 2.0, which prevented the two phases from separating and caused a coprecipitation loss of vanadium.
