I'm new to these forums, but I'm hoping I might be able to get some help with a problem I'm having. I'm working on a project that will (hopefully) produce a continuous stream of bromine via electrolysis of anhydrous hydrogen bromide gas. The actual process of doing the electrolysis is not overly difficult, but I'm trying to come up with a good way to quantify the amount of bromine that is produced so that we can determine the Faradaic efficiency of the reaction. In looking through the literature, it seems that I could try and do some kind of colorimetric measurement or bubble the product stream through an organic solvent, but in each case I'm concerned that the amount of bromine will be under-reported.
Any suggestions on how I might tackle this? Thanks!
