@future’s tek is for distillate.
any suggestions for separating abamectin from high CBD crude? wasn’t planning on going to distillate, at least I wasn’t before running into this issue.
I figure saline washes against crude in hexane at a min.
From what I understand it is more advantageous to remediate 1st pass distillate rather than crude because some pesticides carry over with the terps when distilling. You’d most likely be dealing with less ppms if you remove terps. Boiling point of abamectin is 155C so some would likely come off in de-vol pass. Also abamectin is soluble in acetone, methanol, isopropanol and toluene. If you redissolve crude in acetone and recover it would probably pull some out of oil.

that is also my understanding…hence
My cannabinoids are also soluble in all of those solvents. I would not expect just dissolving in solvent then recovering to achieve any reduction in ppm. unless you’re suggesting abamectin will go with the evaporating solvent, which seems unlikely to me (not a chemist).

I’m not a chemist either but I was told by one that we can reduce piperonyl butoxide and other organic solvent loving pesti by using this method.
I was curious if this remediation method would work on Spinosad and Malathion? Thanks in advance for any insight.
They are both water soluble so brine wash should help a lot, then Magnesium Silicate chromatography to finish. @Dee333

I would expect partitioning, chromatography, or ab/adsorption to be required to significantly reduce the pesticide load.
I guess they might partition into the vapour phase, but I’m dubious…

Anyone peek at this before?

All solvents should be pesticide quality or equivalent. Solvents may be degassed prior to use.
7.10.1 Diethyl ether, C2H5OC2H5 – Must be free of peroxides as indicated by test strips (EM Quant, or equivalent). Procedures for removal of peroxides are provided with
the test strips. liter of ether.
After cleanup, 20 mL of ethyl alcohol preservative must be added to each
Pentane, CH3(CH2)3CH3
Hexane, C6H14
Methylene chloride, CH2Cl2
Acetone, CH3COCH3
Petroleum ether (boiling range of 30 - 60 °C) Toluene, C6H5CH3
2-Propanol, (CH3)2CHOH
Maybe chasing brine pHs isn’t the solution, but multiple florisil passes with a sequence of various solvents?

i think your on to something here!
Google… Solvation Effects…
Something I didn’t NDA, YET…
The smart ones will research (need to do a TON of R&D like I did, spending lots on different solvents for said R&D) and choose to either tell the dumb/lazt ones or wisen up a little bit and not…
You’ll all thank me later.
Thanks to the homie application specific chemist who introduced me to this term… last year 
…
Left most of ya’ll in the dust now 
Catch up if you can!!!

What’s the hottest and deepest under vacuum anyone has steamed a crude oil or distillate?
(steam - aka water vapor)

As long as I stay on top of the tech of the day when it comes to distillate yields and purity, I’m not too worried about the latest “tek” on pesticide remediation, as I ultimately have no desire in general to work with contaminated input product. However, there is of course natural curiosity of cleaning a product as best as possible, the desire to turn trash into something worthwhile by removing as many impurities as possible, and it is probably a good resume builder as well (LOL).
I do expect sweeping changes in the next few years as far as pesticide controls for grows and/or proprietary vertically integrated businesses with their own protocols on what they can spray and how to remove it later on.
But as has been previously stated, this applied science is currently specific to cannabis, as there are no requirements for third-party verified pesticide testing for our food crops. There should be, but its not happening yet.

Brine is cheap, magsil-pr is not.

The magsil method is preferably a two solvent system of ethyl acetate and an alkane like hexane. Please take a peek at the SOP linked on the EPA website.

The SOP proposes various solvents and methods depending on what you are trying to extract.
Would anyone be kind enough to provide me with a picture or description of how to set up the pesticide removal glassware from Lab Society? I am new to remediation and want to make sure I am on the right path. Just got the LS pesticide kit in the mail and am eager to process my first pass material. Thanks in advance !

I thought the polar wash only yielded trace cannabinoids?
Hows that list going? Ive been building one as well
Quick dumb question-
The 60L of saline solution is made in a 50L reactor but subsequently do the 20L pH 9, 6, and 4 washes occur in the reactor as well? Does one then transfer the mix of saline and distillate/heptane into a sep. funnel for separation?
