Case Study

Acid Blue 350 as A Model Dye for Laccase Degradation Performance Assessment

Lee J, et al. Journal of Biotechnology, 2010 (150), 274; Yesilada O, et al. Applied biochemistry and microbiology, 2014, 50, 55-61.

Due to the low biodegradability of industrial dyes, traditional biotechnology is not efficient when dealing with dye wastewater. The enzymatic decolorization of dyes has been tried to overcome this problem. Laccase have proven to have the potential for dye degradation. Due to the high output of laccase, the Funalia Trogii has a good decolorization ability in the processing of dye wastewater than other test fungi.
· Different inductive agents have been tested to promote enzyme production capabilities, including guaiacol, xylidine, CuSO4, MnSO4, ZnSO4 and alcohols. CuSO4 is the most effective in stimulating laccase production (22.8 units in 0.5 mm CuSO4).
· Puritated enzymes that by ultrafiltration and gel permeable chromatography (GPC) can be fixed through alginate, which can be successfully used to degrade a model dye, Acid Blue 350.
· In addition, compared with free enzymes, the obtained fixed enzymes show better stability, activity and reusable use in the reaction process.

The Adsorption of Acid Blue 350 in ZnCl2 Activated Carbon

Demiral H, et al. J. Int. Environmental Application & Science, 2008, 3(5), 381-389.

Taking the hazelnut sugar cane as the raw material and ZnCl2 as the activator, chemical activation carbon is prepared for chemical activation at 600 ° C and 3/1 impregnation ratio. Further, the adsorption performance of the activated carbon material to acid blue 350 (Sandolan Blue) was studied, from aspects of adsorption conditions (pH, stirring time, dye concentration and temperature) and adsorption dynamics. The results show:
· Acid pH is conducive to the adsorption of acid blue 350.
· The adsorbed acid blue 350 dye increases with the increase of dye concentration and temperature.
· The adsorption of the acid blue 350 on the activated carbon is more consistent with the LANGMUIR model.
· When the temperature of 45 ° C and pH is 2, the maximum adsorption capacity of the acid blue 350 dye is 450 mg/g.
