Due to the high concentration

thicken color

great toxicity and bad degradation of the dye wastewater

its treatment is always a difficult subject．Attention has been paid to the application of porphyrin and PcS as photo-catalyst for wastewater treatmem．As a bionic compound

the structure of phthalocyanine sulfonic iron(FePcS)(likep-450)is similar to that of porphyrin modified metal．In this paper

A novel catalyst ofhypercrosslinked resin

named as C-FePcS

was synthesized by using the Friedel-Crafts reaction between FePcS and post-crosslinked beads of chloremethylated polyvinylbenzene-styrene．The catalyst was characterized by diffuse reflectance absorption spectra

and essential conditions of photo reaction were discussed Upon visible light irradiation in the presence of H2O2

this catalyst was found to be hishly effective for the degradation of nonbiodegradable malachite green(MG)in aqueous solutions with decolomess rate of near 100％and total organic carbon(TOC)removal rate of 72％．The influence factors of degradation of MG with visible light at different conditions including acidity

dosage of catalyst were investigated．This catalyst was hardly affected by pH of the solution．A possible reaction mechanism was also proposed．
