[Histonet] Formalin Neutralizer
The topic of formalin neutralization comes up regularly in HistoNet and there are always those who post answers telling about good results obtained and the advantage of eliminating the cost of removal by some local company dedicated to chemical contaminants removal. Perhaps I have been unlucky but I have tried Transform121; Vytak; Formalex; Aldez-AMS 410 and 1% aq. potassium permanganate with very poor results as tested with Schiff's reagent of the neutralized product. Always the neutralized NBF had a strong smell of formalin, as Mark describes. On an answer to HistoNet on March 24, 2009 our colleague Tony Henwwod advised all of us that 10% neutral formalin can be neutralized with sodium bisulfite or with concentrated ammonia (27%) used at a ratio of 56mL every 1 000 mL of 10% NBF. The ammonia is added stirring and is an exothermic chemical reaction. I have not tested the procedure but I completely sure of Tony's advise. After my failures with commercial neutralizers I decided to keep using the services of the chemical disposal company, expensive as they were, because I could reconcile myself with the idea of dumping incompletely neutralized NBF into the sewer and that is what I recommend anybody who, after neutralizing the NBF, still smells it!

Re: [Histonet] Formalin Neutralizer
Lol, of all your post Rene, I have not seen anything that needed more. Your a good guy. Always detailed and precise, with a complete story not just bare minimum effort. In this case I have to point something out, not so much for histonet as for Rene to thank him for all his histonet education he gives us all. So here goes--- formaldehyde is a colorless odorless gas. You cannot smell it. The smell of formalin is an additive, the purpose of which is to make you aware when you are being exposed. Propane has a similar additive that smells like rotten eggs, so you dont blow your house or garage up leaving the stove or grill on all day and then lighting it up! Boom! To elaborate on the formalin neutralizing blah blah- you make hexamethylene tetramine by mixing ammonia and formaldehyde...its a common compound used in platics and other industry and also to treat UTI. Since it is a drug, it is allready found in our water system. Just pour that crap down the drain Rene! Dont worry about the smell its harmless! And keep posting on histonet!

Re: [Histonet] Formalin Neutralizer
Benjamin: Thank you Just a detail about formaldehyde (chemically named methanal). Please check ANY chemical book and you will find in the description of methanal something like: colorless gas at room temperature with a CHARACTERISTIC PUNGENT and IRRITATING ODOR!! So much for you cannot smell it!!! And be assured I will keep posting every time I think I can be of some help to my fellow histonetters René J.
