Abstract
The invention discloses a regeneration method for an aging P204 organic phase. Spherical active carbon is used as a regeneration agent. The regeneration method comprises the following steps: transferring the aging P204 organic phase into a reaction pot, adding 40-50g of the spherical active carbon into each liter of the aging P204 organic phase, and stirring under room temperature for 6-8 hours for filtration, wherein filtrate is a regenerated P204 organic phase, and the yield thereof is 96-98 percent. The regeneration method has the advantages of short technical flow, high regeneration speed, small use amount of chemical engineering reagents, zero emission of waste liquid, simple equipment, operation simplicity and convenience, low regeneration cost and the like.
Description
Technical field
The present invention relates to a kind of renovation process of aging P204 organic phase, particularly relating to a kind of is regenerative agent with spheric active carbon, recovers the method for aging P204 organic extractant phase performance and function.The present invention specifically belongs to solvent extraction technology field.
Background technology
The chemical name of P204 is di-(2-ethylhexyl)phosphoric acid, and this is a kind of essential industry extractant being widely used in the fields such as light rare earth separation, the separation of cobalt nickel, heavy metal element recovery, heavy metal containing wastewater treatment, the reparation of heavy metal pollution farmland.In actual use, usually P204 extractant be dissolved in kerosene or sulfonated kerosene and make organic phase, the mechanism normally cation exchange mechanism of its extracting metals ion.Because P204 organic phase for a long time, periodically goes through the cyclic process such as saponification, extraction, washing and back extraction, amass night day and tire out, therefore inevitably there is various change and occur aging phenomenon in P204 organic phase gradually.P204 organic phase aging is an extremely complicated process, and the open research report of so far there are no this respect, so the current agine mechaism also not understanding P204 organic phase.P204 organic phase after aging, extraction load capacity obviously declines, separative efficiency significantly reduces, phase-splitting time significant prolongation, serious emulsification not even phase-splitting.
Many professional and technical personnel in the field adopt the chemical reagent treatment of aged P204 organic phases such as hydrochloric acid, nitric acid, NaOH, oxalic acid, but all end in failure.End today, owing to not having process of regenerating, when aging P204 organic phase cannot use, the most frequently used Disposal Measures is discarded.Discarded aging P204 organic phase, not only can suffer greater loss economically, and serious environment pollution, impact ecology.
Summary of the invention
The object of the invention is the method for there is no rejuvenating aged P204 organic phase, overcoming the problem of discarded aging P204 organic phase contaminated environment, impact ecology, setting up a kind of method that is easy, rejuvenating aged P204 organic phase fast and efficiently.
The renovation process of a kind of aging P204 organic phase of the present invention, take spheric active carbon as regenerative agent, is transferred in reaction pot by aging P204 organic phase, and often liter of aging P204 organic phase adds that 40g ~ 50g average grain diameter is 0.4mm ~ 0.6mm, BET specific surface area is 500m
2/ g ~ 1000m
2the spheric active carbon of/g, stirred at ambient temperature process 6h ~ 8h, filters; Filtrate is regeneration P204 organic phase, and its yield is 96% ~ 98%.
Advantage of the present invention is: technological process is short, and reproduction speed is fast, 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.Used spheric active carbon, can adopt the processing steps such as salt acid soak, filtration, washing, oven dry and high-temperature activation and regenerate.
Detailed description of the invention
Be further described below in conjunction with the renovation process of specific embodiment to a kind of aging P204 organic phase of the present invention.
embodiment 1:
Aging for 600L P204 organic phase is transferred in 1000L reaction pot, adds that 27kg average grain diameter is 0.5mm, BET specific surface area is 750m
2the spheric active carbon of/g, stirred at ambient temperature process 7h, filters; Filtrate is regeneration P204 organic phase, and its yield is 97%.
embodiment 2:
Aging for 600L P204 organic phase is transferred in 1000L reaction pot, adds that 24kg average grain diameter is 0.4mm, BET specific surface area is 1000m
2the spheric active carbon of/g, stirred at ambient temperature process 8h, filters; Filtrate is regeneration P204 organic phase, and its yield is 98%.
embodiment 3:
Aging for 600L P204 organic phase is transferred in 1000L reaction pot, adds that 30kg average grain diameter is 0.6mm, BET specific surface area is 500m
2the spheric active carbon of/g, stirred at ambient temperature process 6h, filters; Filtrate is regeneration P204 organic phase, and its yield is 96%.
