Just to summarise quickly what is in this attachment, basically nitrogen dioxide can oxidize ammonium sulfate, the reaction proceeding best at
100degC. The NH4+ ions are oxidized to N2. Besson and Rosset, Compt. Rend. 142, (1906) 633.
Just making this post because at some later time someone might be searching through the archives and the link might not work.

How true this is at the moment! Due to the new regulations in the EU both NH4ClO4 and HClO4 are easier to
obtain than KClO4, NaClO4, NH4NO3 and HNO3! Maybe we should start a thread about how to make HNO3 from HClO4 and a nitrate salt 
NH4ClO4 can be obtained from eBay and where I live, HClO4 can be purchased without too much hassle. HNO3 and NH4NO3 on the other hand are gone and all
suppliers who still sold these a year ago now really do not stock this anymore or only sell to companies with the right licenses. Only issue is that
HClO4 is much more expensive than HNO3 was in the past (appr. 7 times as expensive on a liter-basis for 70% concentration). NH4ClO4 also is much more
expensive than NH4NO3 was when it still was available.
