Make sure your Ferric Chloride bottle has a plastic cap. Never use metal caps on Ferric Chloride containers. I only use about 3 cups at a time, and keep reusing it until it takes longer and longer to achieve the same etch results.... Add 10 cm3 iron(III) chloride solution to the flask and then add deionised water to bring volume to 100 cm3 and mix the solution thoroughly. 8. Measure the absorbance of the solution using a

I've just got hold of a nice little PCB etching kit, which uses ferric chloride as the etchant. I know it's re-usable for at least a few etches (though the kit doesn't actually specify an estimated re-use count) but after that I'll need to dispose of the used chemical. I've read the accompanying safety sheet thoroughly, which states that

- Ferric chloride producers tend to have a regional, rather than a national outlook, because transportation costs are significant. More than 80% of all ferric chloride is sold in municipal bids, with 53% sold for municipal wastewater applications, and 37% for potable water treatment applications. Industrial water treatment applications account for 6% of consumption, with the remaining 5% sold in
- 2006. Dissolve the ferric chloride in acidic solution, e.g., dilute sulfuric acid. You will get better dispersion by adding to the wastewater in an acidic stage (if present in your treatment).
- No Ferric Chloride anywhere in sight. Making your own etchant: Fun for the whole family! Then I remembered I’d been thinking of switching to re-usable etchant , created on the bench using muriatic acid (the store name for hydrochloric acid, HCl, used for cleaning swimming pools).
- Anyway, how do you make it? If you react iron (e.g. steel wool) with gaseous HCl, you get FeCl 2. If, instead, you use chlorine gas, which is a stronger oxidising agent, you get FeCl 3.
