摘要: Metal complex perchlorinated iron-phthalocyanine (FePcCl16) was prepared and used as a photocatalyst. The heterogeneous photocatalytic degradation of rhodamine B (RhB) and salicylic acid (SA) by FePcCl16 activated by molecular oxygen (O-2) under ultraviolet light (lambda <= 387 nm) and by hydrogen peroxide (H2O2) under visible light irradiation (lambda >= 420 nm) were studied. The experimental results indicated that organic pollutants can be effectively degraded under both ultraviolet and visible light. Under ultraviolet and visible light illumination, the removal rates of total organic carbon (TOC) for RhB reached 86.24% after 180 min and 64.73% after 300 min, respectively. The degradation process was predominated by the hydroxyl radical (center dot OH), according to the results from benzoic acid fluorescence method. The hydrophobic photocatalyst FePcCl16 was stable in aqueous solution. The photocatalytic degradation system had wide pH adaptability (3-11). The heterogeneous photocatalyst can be reused to degrade toxic organic pollutants both under ultraviolet and visible light.
