Abstract
The invention provides a regeneration method of an aged P507 organic phase. The method is that micro-spherical silochrom is used as a regenerant, and the aged P507 organic phase is transferred into a reaction vessel, wherein 20-30g micro-spherical silochrom is added to the aged P507 organic phase per liter, and the mixture in the reaction vessel is agitated for 8 to 10 hours at the room temperature and then filtered to obtain filtrate, wherein the filtrate is the regenerated P507 organic phase of which the yield is 97-99%. The method has the advantages that few steps are carried out, the regeneration costs a little time, few chemical agents are used, no waste liquid is discharged, devices are simple, the operation is simple and convenient, and the regeneration cost is low.
Description
Technical field
The present invention relates to a kind of renovation process of aging P507 organic phase, be specifically related to a kind of with microspheroidal silochrom for regenerator, recover the method for aging P507 organic extractant phase performance and function.The present invention specifically belongs to solvent extraction technology field.
Background technology
P507 is that industrial separation of mixed rare-earth prepares the most frequently used extraction agent of high-purity single rare earth product.When reality uses, usually will be dissolved in kerosene or sulfonated kerosene with P507 and form organic phase.Because P507 organic phase constantly periodically recycles, the extraction agent P507 therefore in organic phase inevitably changes gradually and occurs catabiosis.The agine mechaism of P507 organic phase is very complicated and current research is still not deep enough, so far to the agine mechaism of P507 organic phase or not clear.Problem is: the P507 organic phase after aging, not only outward appearance generation noticeable change, and such as transparency declines, opacity rises, color burn; And the extracting power of P507 organic phase, phase-splitting performance and extracting and separating efficiency significantly decline, and even cannot use time serious.For a long time, owing to there is no the method for rejuvenating aged P507 organic phase, when aging P507 organic phase cannot use, have to discard.Discarded aging P507 organic phase, not only has heavy losses economically, and serious environment pollution.For this reason, Zhong Xueming reports " aging P507 extractant regeneration research " (In Jiangxi Science, 2002 the 20th volume the 1st phase 31st ~ 33 pages), proposes with a kind of P507 renovation process being still in confidential state so far.On the one hand, this report is maintained secrecy to regenerator, and therefore this process of regenerating is also really not open; On the other hand, the main drawback of the method is that regeneration treatment time is longer.
Summary of the invention
The object of the invention is to there is no disclosed renovation process and undocumented renovation process for aging P507 organic phase and there is treatment time longer shortcoming, propose a kind of method that is easy, rejuvenating aged P507 organic phase fast and efficiently.
The renovation process of a kind of aging P507 organic phase of the present invention, with microspheroidal silochrom for regenerator, aging P507 organic phase is transferred in reactor, add the microspheroidal silochrom that 20g ~ 30g granularity is 20 order ~ 50 orders, mean pore size is 9.0nm ~ 11.0nm, pore volume is 0.8ml/g ~ 1.0ml/g in often liter of aging P507 organic phase, filter after stirred at ambient temperature process 8h ~ 10h; Filtrate is regeneration P507 organic phase, and its yield is 97% ~ 99%.
Advantage of the present invention is: processing step is few, and regeneration treatment time is short, and chemical reagent consumption is few, and without discharging of waste liquid, equipment is simple, and easy and simple to handle, regeneration cost is low.
