Case Study

Biocatalytic Reaction Decolorization Pathway of Acid Blue 129

Wang, Ya-Jing, et al. Applied Biochemistry and Biotechnology, 2020, 192, 861-880.

Biocatalytic decolorization of acid blue 129 (AB129) can be achieved using immobilized recombinant horseradish peroxidase C1A (HRP C1A). During this process, AB129 has a remarkable decolorization effect, and its decolorization rate can reach 76.3±1.6%.
Decolorization mechanism of acid blue 129
· The decolorization of AB129 by HRP C1A was a step-by-step process. In the mechanism, the oxidative HRP C1A (II) and HRP C1A (III) attacked the unsaturated conjugated bonds in the chromophore of the dye molecule, resulting in unsaturated bond breakage.
· Thereby, the dye organic macromolecules were oxidatively decomposed to form organic and inorganic small molecules. The dye solution was decolorized and degraded by changing the molecular structure of the dye.

Adsorption Removal of Acid Blue 129 by Polymer Composites

Kukulski T, et al. Polymers, 2020, 12(5), 1051.

Textile wastewater treatment is considered an important branch of environmental chemistry. Acid blue 129 dye (AB129), as a typical dye model, can be essentially removed by adsorption on the prepared reduced graphene oxide/polyaniline (rGO/PANI) composite. The maximum capacity of AB129 on rGO/PANI composites (using Langmuir isotherm) can reach 25.57 mg/g.
Adsorption experiment for acid blue 129
· AB129 solutions (25 mg/L) were prepared by adding dye to deionized water.
· Adsorption tests were performed in 100 mL beakers (50 mL of 25 mg rGO/PANI composite dispersion).
· Samples were centrifuged at 14500 RPM and spectrophotometrically measured using a UV-visible spectrophotometer.
· All samples were subjected to kinetic experiments at room temperature for 60 min. A kinetic model was then used to determine the adsorption control mechanism based on the experimental data.

Acid Blue 129 Used for Intercalation Modification of ZnAl Layered Double Hydroxide

Yang L, et al. Industrial & Engineering Chemistry Research, 2014, 53(46), 17961-17967.

By co-precipitating acid blue 129 (AB129) and sodium salicylate (SA) into the interlayer channels of ZnAl layered double hydroxide (LDH), an organic-inorganic hybrid pigment (AB129- and SA-cointercalated LDHs, ZnAl-AS LDHs) with improved photostability can be successfully synthesized.
Preparation procedure of ZnAl-AS LDHs
· A mixture of Zn(NO3)2·6H2O (5.0 mmol), Al(NO3)3·9H2O (2.5 mmol), SA, and AB129 was dissolved in water (70 mL) by vigorous stirring under a N2 atmosphere at 50 °C in a water bath.
· An alkali solution (30 mL) containing 18.0 mol of NaOH was added dropwise into the mixed solution with vigorous stirring under a N2 atmosphere. The resulting slurry was then aged at 95 °C with violent agitation under a N2 stream for 6 h.
· The product cake was washed with hot deionized water for eight repetitive centrifugation and dispersion cycles and with ethanol for three cycles, and the collected cake was dried at 100 °C in an oven for 12 h.
