trapping H2S

Dear Mark,

You should try the standard method for absorbing H2S which is cadmium
chloride. My student (some years ago now) Hamid Abdollahi used 3 reaction
bottles in series containing 100 ml 1% CdCl2. This is a basis for a good
standard method for measuring H2S since cadmium sulphide is very insoluble.
Simply filter the cotents of the bottles and dry to constant weight!

Good luck!

Julian
