Abstract

The renovation process of a kind of aging C272 organic phase of the present invention take diatomite as regenerator.Be transferred in reactor by aging C272 organic phase, often liter of aging C272 organic phase adds 50g ~ 60g diatomite, filters after stirred at ambient temperature process 10h ~ 12h, and filtrate is regeneration C272 organic phase, and its yield is 94% ~ 96%.It is short that the present invention has technical process, and reproduction speed is fast, and chemical reagent consumption is few, and without discharging of waste liquid, equipment is simple, easy and simple to handle, the advantages such as regeneration cost is low.

Description

A kind of renovation process of aging C272 organic phase
Technical field
The present invention relates to a kind of renovation process of aging C272 organic phase, particularly relating to a kind of is regenerator with diatomite, recovers the method for aging C272 organic extractant phase performance and function.The present invention specifically belongs to solvent extraction technology field.
Background technology
C272(Cyanex272) chemical name is two (2,4,4 tri-methyl-amyls) phosphonic acids, mainly for separating of the organophosphorous extractant of non-ferrous metal element especially cobalt and nickel.In actual use, usually C272 extraction agent be dissolved in kerosene or sulfonated kerosene and make organic phase, the mechanism of its extracting metals ion is generally cation exchange mechanism.Because C272 organic phase recycles for a long time, therefore inevitably there is various change and occur catabiosis in C272 organic phase gradually.C272 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 C272 organic phase.From organic phase in appearance, the weathering process of C272 organic phase is that a transparency is by clear feculence, color change procedure from light to dark.C272 organic phase after aging, extraction charge capacity obviously declines, separation factor reduces, separation efficiency significantly reduces, phase-splitting time significant prolongation, serious emulsification not even phase-splitting.
Because extraction agent C272 is expensive, therefore many professional and technical personnel in the field have employed all chemical reagent and technique means carries out manipulation of regeneration to aging C272 organic phase, and attempt recovers aging C272 organic extractant phase performance and function.But result is regrettable, all end in failure.Owing to there is no successful renovation process, when aging C272 organic phase cannot use, current Disposal Measures is normally discarded.Discarded aging C272 organic phase, not only can sustain a great 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 C272 organic phase, overcoming the problem of discarded aging C272 organic phase contaminate environment, impact ecology, setting up a kind of method that is easy, rejuvenating aged C272 organic phase fast and efficiently.
The renovation process of a kind of aging C272 organic phase of the present invention take diatomite as regenerator.Aging C272 organic phase is transferred in reactor, adds 50g ~ 60g diatomite in often liter of aging C272 organic phase, after stirred at ambient temperature process 10h ~ 12h, filter; Filtrate is regeneration C272 organic phase, and its yield is 94% ~ 96%.
Advantage of the present invention is: technical 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.
Embodiment
Be further described below in conjunction with the renovation process of specific embodiment to a kind of aging C272 organic phase of the present invention.
embodiment 1:
Aging for 600L C272 organic phase is transferred in 1000L reactor, adds 33kg diatomite, stirred at ambient temperature process 11h, filter; Filtrate is regeneration C272 organic phase, and its yield is 95%.
embodiment 2:
Aging for 600L C272 organic phase is transferred in 1000L reactor, adds 30kg diatomite, stirred at ambient temperature process 12h, filter; Filtrate is regeneration C272 organic phase, and its yield is 96%.
embodiment 3:
Aging for 600L C272 organic phase is transferred in 1000L reactor, adds 36kg diatomite, stirred at ambient temperature process 10h, filter; Filtrate is regeneration C272 organic phase, and its yield is 94%.
