Diffusion of bromine vapour IOPSpark

The main diffusion tube is a closed tube (45 cm long, 5 cm in diameter} with only one opening to a side tube.There is, therefore, no danger of an accident releasing bromine to the pump when diffusion into a vacuum is done.

Mass diffusivity - Wikipedia

  

2019-10-11  Diffusivity, mass diffusivity or diffusion coefficient is a proportionality constant between the molar flux due to molecular diffusion and the gradient in the concentration of the species (or the driving force for diffusion). Diffusivity is encountered in Fick's law and numerous other equations of physical chemistry. The diffusivity is

Bromine as a disinfectant - Lenntech

A bromine-containing stick was developed in 1958, because of the risks of using fluid bromine. This stick exists of bromine-chlorine-dimethylhydantoin (Dihalo, DMH).Both chlorine and bromine are attached to a nitrogen atom, which acts as an organic support. Applied to water, DHM is hydrolyzed and forms hypochlorous acid.
