electrodialysis for gakk/p-eph seperation

(1/2) > >>

stratosphere:
i was not able to find any info on the TFSE, but it occured to me that electrodialysis ( http://www.electrosynthesis.com/ess/weid.html ) using a cation permeable membrane could be used to extract p-eph from pill mess or possibly eph from plant mess, for example using a polystyrene sulphonic acid membrane the negative cell containing dilute acid, the positive cell containg slightly acidic pill solution.
has any bee dreamed of such a system before?

WizardX:
Very similar to ion-exchange chromatography, only here the electrical field potential helps drive the ions to separate.

dwarfer:
Precleaning of some amendments will have to be effected in order to
eliminate the effect of the poly ampholytes, whose physical confirmation is dynamic,  and whose multi-charged (+&-) lenght will interfere greatly with the hypothesis.

Past threads on improved electro methods, and even the
Tyvek threads, will provide some inspiration.

In the 3 cell electro device I made,
the suspended vertical graphite anode
within a condom,
could suffice for part of the structure.

A larger outer "basket" of either Tyvek or a purchased
membrane could be used,
and the outer electrode could be ring of lead, 
or assembled carbon electrodes arranged appropriately.

jboogie:
the tyvek threads? i mean, they are still there, but why dont bees speak of the tyvek? ive been a member of the hive for quite some time (multiple names over the years) and i remember the promise of the tyvek threads. do the new gaks render tyvek useless? what did i miss? ::)

ChemoSabe:
Tyvek worked awesomely until polysorbate 80's introduction at the dawn of 2004.

Orange gakk 2 sort of got through it but could be killed off with Geezes Xylene precipitation technique.

Swim's buddy never saw any of the problems reported due to Orange Gakk 1 make it through any tyvek extractions.

Polyethylene glycol will not be fully stopped by tyvek from coming over. But the freeloading PEG can easily be removed with a "panning for gold" style acetone rinse.

A weirdly reduced product was still possible of psuedo tyvek extracted with pills containing PS80 but was of the undesirable "jaw clench" variety. Yeilds sucked royally because of the amphoteric qualities the PS80 imparts to both the pseudo and the end product. (amphoteric - when a compound starts acting like both an acid and a base ie: soluble in both polars and non polars)

Don't know how it does with eudragit but since most eudragit contaminated pillstocks also contain PS80 most likely any product made would be the underreduced "jaw clench" grade or worse.
