It's not complicated at all. This is the "official" procedure. If you use it correctly you're guaranteed to safely dispose of any hazardous cyanide
spills.

High-dose ascorbic acid Is a good method for cyanohydrin glucosides, as a rule it should also act on inorganic cyanides.

I see, great thank you.
I’ll have to translate this but I guess I have to.

studies in guinea pigs. If I was poisoned with cyanide I would definitely try it instantly.

Hydrogen cyanide has really low pKa, it can be released from cyanide solutions even by H2CO3 that is being produced from atmosphere CO2.
I wouldn't mix it with any acid, I would use alkaline bleach solution

Looks like several people don't need their cyanides anymore. The rest is still try to figure out something ...

i think heating with Sulfur or adding sodium thiosulfate is good way to go. while you at it maybe make some prussian blue.

You need to read that more carefully. The paper says .
High-dose ascorbic acid decreases detoxification of cyanide derived from amygdalin (laetrile): studies in guinea pigs.
Vitamin C stops the guinea pigs from destroying cyanide (by reaction with sulphur donors).

Yes, they are interesting.
Buty they do not answer my question.
They refer to cyanide possibly messing up the measurement of vitamin C and to the use of vitamin C to prevent chlorine messing up measurements of
cyanide.
(and to the fact that vitamin C actually makes some cyanide derivatives more toxic to guinea pigs)
