AbstractHeterogeneous dark Fenton and photocatalytic degradation of azo-dye chrysoidin were studied using natural marmatite from a Colombian gold deposit as catalysts. Marmatite is composed of zinc sulfates, iron sulfates and iron oxides; due to this composition marmatite is an active material in the degradation of chrysoidin. Marmatite was characterized by SEM, XRD, BET and XRF. Experimental results allow concluding that the dye was oxidized (degraded) in both, heterogeneous Fenton and photo-catalyst reactions, using Marmatite as catalyst. The variables considered were solution pH, marmatite concentration, C
