摘要

Bitter gourd peroxidase immobilized on the surface of concanavalin A layered calcium alginate-starch beads was used for the successful and effective decolorization of textile industrial effluent. Effluent was recalcitrant to the action of bitter gourd peroxidase; however, in the presence of some redox mediators, it was successfully decolorized. Effluent decolorization was maximum (70%) in the presence of 1.0 mM 1 -hydroxybenzotriazole within 1 h of incubation. However, immobilized bitter gourd peroxidase showed maximum decolorization at pH 5.0 and 40 ℃. Immobilized bitter gourd peroxidase decolorized more than 90% effluent after 3 h of incubation in a batch process. The two-reactor system, one reactor containing immobilized peroxidase and the other had activated silica, was quite effective in the decolorization of textile effluent. The system was capable of decolorizing 40% effluent even after 2 months of continuous operation. The absorption spectra of the untreated and treated effluent exhibited a marked difference in absorbance at various wavelengths. Immobilized peroxidase/1 -hydroxybenzotriazole system could be employed for the treatment of a large volume of effluent in a continuous reactor.
