Hexvalent Chromium Test Results

This just came up on Youtube
So I thought I would post for all to see.

YouTube - Myth or Truth, is Hexavalent Chromium in the Electrolyte

[Gre]

I was just about to post this as well...

Is the brownish-red coloration of the water caused by hexavalant chromium?

[goldenequity]

Yup.
A $20 test kit which confirms presence of Hexvalent Chromium in (any and all) electrolyte solutions running Stainless Steel electrodes.

Whether there's more from 304SS or less from 316L SS... I don't know..... it's toxic that's for sure as all SS electrodes (mostly the anode) will sacrifice into solution.

Concentration levels will obviously build up the longer you continue use of the same electrolyte solution and just keep "topping it off" with water.

Thanks to this guy for ponying up for the test kit and youtubing it for all to see.

It would have been a little more scientific if he did a plain tap water test along side of it, but oh well..

How do you get rid of it, or safely dispose of it? OxiClean? lol.

Here's some information on neutralizing the Hexavalent Chromium, if anyone is interested.

Excellent post

Thanks Gre for posting that link!

So... Ferrous Sulphate and Lime will render toxic Cr(VI) into benign Cr(III)!
very good news.
I am researching whether Magnesium Sulfate would work as well,
if so,
everyone can easily obtain Epsom Salt from Wal Mart
and Lime from the Lumber Yard.

Alternate Method

Good News!

I chatted with a friend of mine who researched this as well.
He found out that the State of Illinois/Chicago deals with this issue in a much
simpler way:

Simply raise (or lower) the pH of your spent electrolyte to a neutral 7pH.
The Cr(VI) will change to a benign Cr(III)... TriValent Chromium
and precipitate out of solution as a flocculant (fluffy mush!)

This can be filtered off and disposed of as a Non Hazard material.
nice!

Hexvalent testing is the best in know about the speciation of the chemicals. There are many companies which are working on this but our company is one of the best in this. You can get help with the help of our company about it.

Thanks George, that was very useful.

I'm not George

Sorry I accidently misled you. I contacted George Wiseman and that was a copy/paste of the e-mail he sent me.

Ok, Thanks for the clarification. I thought it was George!
