Sublimation of Iodine

[linotas]

Are we still able to do this? A couple of the teachers have requested it but my HOS has said she thinks that we are not allowed to anymore.
Of course its fallen to me to find out.....

We still do it. Just 2 or 3 crystals in a gas jar with the lid on. Then to the fume cupboard we go!

Thanks, thats how we were going to do it. How do you dispose of the iodine after use? This is one of my weak areas now I'm not in a medical lab where we paid someone to take everything away for us MSDS's are no use as they all so "according to local regs blah blah blah" which I dont know and cannot find.

I put sodium thiosulfate on the iodine and mix until there is no brown colour left then dispose of to sewer.

Could always add some ethanol or potassium iodide and store it as iodine solution? waste not want not!

I have a sealed flask which I use as my "Demo" for sublimation of Iodine, and I don't let the cherubs do it themselves.
