Benjaman Posted October 1, 2016 Share Posted October 1, 2016 So I decided to make an electrolysis tank and try it out, I got a big tub from Walmart and grabbed 2 peices of stainless from work. Worked out pretty good! Made wire wheeling this thing a dream! Before and after pics, 152 lb Budden Quote Link to comment Share on other sites More sharing options...
Yuppiejr Posted October 1, 2016 Share Posted October 1, 2016 Nice looking anvil! Problem - stainless steel contains chromium, which is consumed during the process (bet your tank turned an interesting shade of yellow) and is a known skin irritant and, ultimately, carcinogen that's rightly considered hazardous waste for disposal. Your electrodes should be high carbon steel, not stainless. Quote Link to comment Share on other sites More sharing options...
Benjaman Posted October 1, 2016 Author Share Posted October 1, 2016 Why high carbon vs low? Is there an advantage? Quote Link to comment Share on other sites More sharing options...
redeeman Posted October 2, 2016 Share Posted October 2, 2016 I believe sugar neutralizes the hexavalent chromium particles, so before disposing of the water, pour some sugar in the water and stir Quote Link to comment Share on other sites More sharing options...
matto Posted October 2, 2016 Share Posted October 2, 2016 I have always used mild steel or rebar for the electrods. Has always worked. Quote Link to comment Share on other sites More sharing options...

I would like to add that information and reference to the site. Electrolysis does clean up rust really nice, doesn't it. Quote Link to comment Share on other sites More sharing options...
redeeman Posted October 2, 2016 Share Posted October 2, 2016 I cant remember where i initially read it, but, i found on google searching "sugar hexavalent chromium" an article: https://www.technologyreview.com/s/407647/neutralizing-toxic-chromium-with-sugar/ citing a paper called "Sweet solution for chromium pollution" published in sciencenow daily news, 29 march 2007 Quote Link to comment Share on other sites More sharing options...
Yuppiejr Posted October 3, 2016 Share Posted October 3, 2016 .. sorry, not sure why I added the "high" carbon to my response, I typically grab rebar out of the scrap pile for my e-tank. That's a great tip on the use of sugar! Quote Link to comment Share on other sites More sharing options...

redeeman Posted October 3, 2016 Share Posted October 3, 2016 maybe also recommend to dispose of it at a municipal waste station? Dont know about other countries, but in Denmark theres recycling centers in every municipality, and you can get rid of dangerous goods etc which is then sent to decontamination and such Quote Link to comment Share on other sites More sharing options...
Yuppiejr Posted October 3, 2016 Share Posted October 3, 2016 One follow-up comment on the sugar option - it seems like a majority of the harmful hexavalent chromium will bond with the sugar to form Chromium III at a 93-94% rate, not 100%. The pollutant is still present and may require the same disposal methods as the untreated waste, I still wouldn't be pouring it onto the ground near near my house where it is likely to find it's way into the water table and ultimately my well. I'd avoid dealing with it entirely by only using carbon steel electrodes, and even then let the liquid evaporate and then bag the resulting solid/powders as household waste to be disposed of at an approved facility the next time you drop off paints/solvents/oil/etc.. I assume many of these anvils and other tools were painted or slathered with the cheapest oil/grease available at some point in their history to prevent rust in storage/transport, and the likelihood of their being lead or other harmful chemicals present along with the rust that electrolysis removes is pretty high.

SLAG Posted October 3, 2016 Share Posted October 3, 2016 Enter the party pooper. The sugar that complexes with and converts poisonous hexavalent chromium to the "natural" and non-poisonous form is not common table sugar. That sugar is sucrose. The sugars that do the trick are fructose and also glucose. Fructose is known as fruit sugar. It and glucose are mono-saccharides. Table sugar also, known as sucrose, is a double sugar (called a disaccharide). It is a molecule made up of one glucose and one fructose. (stuck together.) In other words, adding table sugar to a chrome-water solution will not work. Fructose sugar can be bought but it may be expensive. But I believe, if my memory serves me, it can be obtained where canning supplies are sold. Apples have a lot of fructose and apple juice would work. But it is not that cheap. Starch is broken down into sucrose then into it a mixture of glucose and fructose. That mixture is called invert sugar which is the preferred sugar used by bakers. That would do the job High fructose corn syrup would also work but I do not know where to get that. It is used in the food and drink industries. Corn syrup is a glucose syrup, and that can be used as well. Soooo. to make a long story table sugar will NOT do the job. It is best used for coffee and corn flakes SLAG.

Charles R. Stevens Posted October 3, 2016 Share Posted October 3, 2016 So use soda pop, phosphoric acid and high fructose corn syrup.... And at about $.50 a litter.... Quote Link to comment Share on other sites More sharing options...
SLAG Posted October 3, 2016 Share Posted October 3, 2016 Thanks Charles, I was not aware that high fructose was commonly sold. That will do the trick. Live and learn. SLAG. Quote Link to comment Share on other sites More sharing options...

Frosty Posted October 3, 2016 Share Posted October 3, 2016 Ah, giving doctors a little indigestion is good for them they tend to think too much of their opinions sometimes. Nurses can be the worst for the "I'm a Medical Professional, you're just an ignorant . . . patient" attitude. A lot of that comes from having a very hard job, not great pay, lousy if any benefits and dealing with nitwits and curmudgeons all day. My endocrinologist and neurologist are great docs. They talk with people not at them. My general is good too but not great, her nurses are . . .typical. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...

Frosty Posted October 7, 2016 Share Posted October 7, 2016 Hospital staff don't seem to have good medical plans either. Their pay isn't bad, just not really good enough to balance the unpleasantness of the work. Pay scales here are generally higher than down south but the cost of living is quite a bit higher, they almost balance out. Frosty The Lucky.

kjbarth Posted September 20, 2018 Share Posted September 20, 2018 Resurrecting an old topic.... Have a 170lb Fisher in a bucket for about 24 hours now and the electrolysis seems to be working well. Can the water and sodium carbonate solution be re-used after skimming/cleaning out the rust from the solution? If so, for how many uses does the electrolysis solution remain effective? I've got 4 anvils and a bunch of hammers and a bunch of other smithing tools that weren't high enough off the ground when flood waters flowed through my garage and shop and I want to get them cleaned up. Thank you. Quote Link to comment Share on other sites More sharing options...
arkie Posted September 21, 2018 Share Posted September 21, 2018 The electrolyte solution can be reused after cleaning it up, but if it's REALLY "crudded up", why not just go ahead and mix up a new batch. The water and sodium carbonate are not that expensive, <wink> I've reused mine quite a bit after doing small stuff like wrenches, horseshoes, small parts, etc. Quote Link to comment Share on other sites More sharing options...
Glenn Posted September 21, 2018 Share Posted September 21, 2018 Scoop the crud off the top, and decant the rest to get to the muck on the bottom. Long as it works it is ok in my experience. As Arkie said, new solution is cheap. Quote Link to comment Share on other sites More sharing options...
