Title:
FENTON REACTION CATALYST USING COFFEE GROUNDS OR TEA DREGS AS RAW MATERIAL
Document Type and Number:
WIPO Patent Application WO/2011/121832
Kind Code:
A1
Abstract:
Disclosed is a fenton reaction catalyst which can maintain iron in a divalent state stably over a long period. Further disclosed is a fenton reaction catalyst which, unknown in conventional technology, can reduce trivalent iron (a cheap iron feedstock) to divalent iron for use. Also disclosed is a fenton reaction catalyst formed having as an active component the reaction product obtained by mixing in the presence of water an iron feedstock containing divalent or trivalent iron and a reduction action component feedstock comprising crushed and roasted coffee beans (in particular coffee grinds) or tea leaves (in particular tea dregs). Further disclosed are a sterilization method which can generate hydroxyl radicals from hydrogen peroxide using the aforementioned fenton reaction catalyst, a pollutant decomposition method, and a light emitting method using chemiluminescence.
