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 40-50 g 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 faciess, more particularly to one kind is with spheric active carbon as again
Raw agent, the method for recovering aging P204 organic extractant phases performance and function.The present invention particularly belongs to solvent extraction technology field.
Background technology
The chemical name of P204 is di-(2-ethylhexyl)phosphoric acid, and this is that one kind is widely used in light rare earth separation, cobalt nickel point
The essential industry extractant in field such as repair from, heavy metal element recovery, heavy metal containing wastewater treatment, heavy metal pollution farmland.
During actually used, generally P204 extractants be dissolved in into kerosene or sulfonated kerosene and make organic faciess, its extracting metals ion
Mechanism be typically cation exchange mechanism.Due to P204 organic faciess long-time, periodically after saponification, extraction, wash and
The cyclic process such as back extraction, product night day tires out, therefore P204 organic faciess inevitably gradually occur various change and occur old
Change phenomenon.The aging of P204 organic faciess is an extremely complex process, and so far there are no, and the open of this respect studies report, so
At present it is not understood that the agine mechaism of P204 organic faciess.P204 organic faciess after aging, extraction load capacity is decreased obviously, separates effect
Rate is greatly lowered, the split-phase time significantly extends, serious emulsification not even split-phase.
Many professional and technical personnel in the field are using chemical reagent treatment of aged such as hydrochloric acid, nitric acid, sodium hydroxide, oxalic acid
P204 organic faciess, but end in failure.Cut-off today, due to without process of regenerating, when aging P204 organic faciess without
When method is used, the most frequently used Disposal Measures are discarded.Aging P204 organic faciess are discarded, larger damage not only can be economically suffered
Lose, and serious environment pollution, impact ecology.
The content of the invention
The purpose of the present invention is the method for there is no rejuvenating aged P204 organic faciess, overcomes discarded aging P204 organic faciess
Pollution environment, the problem for affecting ecology, set up a kind of easy, fast and efficiently rejuvenating aged P204 organic faciess method.
A kind of renovation process of aging P204 organic faciess of the present invention, with spheric active carbon as regenerative agent, aging P204 is had
Machine phase transfer to reaction pot, per liter of aging P204 is organic be added to 40 g～50 g mean diameters be 0.4 mm～0.6 mm,
BET specific surface area is 500 m2/ g～1000 m2The spheric active carbon of/g, h～8 h of stir process 6 under room temperature is filtered；Filtrate
To regenerate P204 organic faciess, its yield is 96%～98%.
It is an advantage of the invention that：Technological process is short, and reproduction speed is fast, and chemical reagent consumption is few, without discharging of waste liquid, equipment letter
Single, easy to operate, regeneration cost is low.Used spheric active carbon, can be using soak with hydrochloric acid, filtration, washing, drying and height
Temperature activation etc. processing step and regenerate.
Specific embodiment
Further is made to a kind of renovation process of aging P204 organic faciess of the present invention with reference to specific embodiment
Description.
Embodiment 1：
The aging P204 organic faciess of 600 L are transferred in 1000 L reaction pots, 27 kg mean diameters of addition be 0.5 mm,
BET specific surface area is 750 m2The spheric active carbon of/g, the h of stir process 7 under room temperature is filtered；Filtrate is organic for regeneration P204
Phase, its yield is 97%.
Embodiment 2：
The aging P204 organic faciess of 600 L are transferred in 1000 L reaction pots, 24 kg mean diameters of addition be 0.4 mm,
BET specific surface area is 1000 m2The spheric active carbon of/g, the h of stir process 8 under room temperature is filtered；Filtrate is organic for regeneration P204
Phase, its yield is 98%.
Embodiment 3：
The aging P204 organic faciess of 600 L are transferred in 1000 L reaction pots, 30 kg mean diameters of addition be 0.6 mm,
BET specific surface area is 500 m2The spheric active carbon of/g, the h of stir process 6 under room temperature is filtered；Filtrate is organic for regeneration P204
Phase, its yield is 96%.
Claims (1)
1. a kind of renovation process of aging P204 organic faciess, it is characterised in that：Described renovation process is with spheric active carbon as again
Raw agent, aging P204 organic faciess are transferred in reaction pot, and the average grains of 40 g～50 g are added in per liter of aging P204 organic faciess
Footpath is 0.4 mm～0.6 mm, specific surface area is 500 m2/ g～1000 m2The spheric active carbon of/g, stir process 6 under room temperature
