H2S + Oxone + UV --> H2SO4


Here's a novel gas scrubbing system utilising UV & Oxone which might be of interest to the Euro folks..

That sounds very useful. I'll be sure to try it out once I have a fume hood, in case anything leaks.

Maybe it'd also be a useful route to sulfuric acid?

S + [Metal] = MS

MS + [Acid] = H2S

H2S + KHSO5 + UV = H2SO4




Collected elements:
Al, Cu, Ga, C (coal), S, Zn

Collected compounds:

Inorganic:
NaOH; NaHCO3; MnCl2; MnCO3; CuSO4; FeSO4; aq. 30-33% HCl; aq. NaClO; aq. 9,5% ammonia; aq. 94-96% H2SO4; aq. 3% H2O2

Organic:
citric acid, sodium acetate, sodium citrate, petroleum

You can make H2S directly S +Paraffin wax + heat = H2S

Regarding synthesis of the sulfuric acid even if it could be performed in an amateur lab it is much easier, cheaper and safer to just buy sulfuric acid, if you need only small amount of it you can use an old amateur method, electrolising CuSO4 solution using lead electrodes or if you really want to make your own acid I would rather opt for oxidazing SO2 using metal oxides, Fe2O3 works reasonably well, hell, you can even buy V2O5 since you need only catalytic amounts.

Also, note that this paper is written by the Chinese they are known for submitting flawed or fabricated results and generally can not be trusted.

I have no qualms with observations of tendencies of cultures of nations as a whole, positive or negative. But may I ask you:
By chance do you have any references , to exemplify said flawed or fabricated results? And were the results later debunked also in scientific publications?

Thanks
P.S. I am not Chinese.
