Claims (8)
1. Förfarande för oxidation av vanadin till ett oxidations-stadium V, där oxidationsmedlet tillsättes i en vattenhaltig syralösning av vanadinet i ett lägre oxidationsstadium än V vid en temperatur av 0 - 80° och oxidationsmedlet hälles i lösning ända tills ätminstone nägot vanadin oxiderats tili oxidationsstadiet V, kännetecknat därav, att san oxidationsmedel användes en vattenhaltig syralösning av peroxo-monosvavelsyra, som innehäller mindre än 1 mol väteperoxid per mol peroxomonosvave1syra.
2. Förfarande enligt patentkrav 1, kännetecknat därav, att peroxcmonosvavelsyra användes i en vattenhaltig syralös-ning, som innehäller mindre än 1 mol väteperoxid per 6 mol per-oxomono svave1syra.
3. Förfarande enligt patentkrav 1 eller 2, kännetecknat därav, att peroxomonosvavelsyralösningen erhälles genom att utföra reaktion mellan vattenhaltig väteperoxid med en stvr-ka av 60 - 75 viktprocent och svavelsyra med en styrka av ätminstone 90 viktprocent, varvid molförhällandet H^SO^ : ^2^2 är i omrädet 2,5 : 1 - 4 : 1.
4. Förfarande enligt nägot av patentkraven 1-3, kännetecknat därav, att vanadinlösningen hailes i pH-omrädet 1-3.
5. Förfarande enligt patentkrav 4, kännetecknat därav, att vanadinlösningen innehäller järn och dess pH hälles i pH-omrädet 1-2.
6. Förfarande enligt nägot av föregäende patentkrav, kännetecknat därav, att vanadinets elektriska spanning kon-trolleras under oxidationen och tillsättes med detta reagerande peroxomonosvavelsyra ända tills den förutbestämda avbrottspunk-ten uppnäs.
