Case Study

Structure and Analytical Methods of Anthraquinone Dyes

Dulo, B., et al. Waste Biomass Valor, 2021, 12, 6339-6374.

Anthraquinone is a polycyclic aromatic hydrocarbon compound that is commonly found in various dyes and pigments, and acid blue 43 is one of them. Anthraquinones contain an anthracene core and two carbonyl groups (usually located on the B ring), and the quinone structure allows for different substitution patterns. There are currently many methods used for the analysis of quinone compounds, which can also be used as reference methods for the analysis and detection of acid blue 43.
Various methods for quinone analysis
· Quantitative methods for quinone analysis include titration, chromatography, UV-visible spectroscopy, infrared spectroscopy, nuclear magnetic resonance (NMR), elemental analysis (EA), degradation analysis (DA) and Raman spectroscopy (RS), etc.
· Qualitative analysis methods for quinone analysis are mainly completed through color reactions. For example, tests based on Bornträger and alkaline reagents can be used for preliminary screening to detect anthraquinones.

Bacterial Degradation of Anthraquinone Dyes

Hai-Hong Li, et al. J Zhejiang Univ Sci B. 2019, 20(6), 528-540.

Acid blue 43 (AB43) is one example of anthraquinone dye, which contains anthraquinone chromophore. Most anthraquinone dyes are resistant to degradation due to their complex and stable structures. Degradation of anthraquinone dyes by bacteria may be a feasible strategy for treating printing and dyeing wastewater. The reported acid blue 43 dye-degrading strain is Escherichia coli DH5α, with a degradation rate greater than 20%. Degradation conditions were pH=7, temperature 37 °C, and shaker speed 150 r/min.
Mechanisms of bacterial anthraquinone dye removal
· The decolorization of dyes by bacteria may result from adsorption or biodegradation. In the process of adsorption, cell mats become deeply colored, whereas those that retain their original color undergo biodegradation. Many studies have reported degradation pathways for azo dyes, but there is little research focused on the bacterial degradation mechanisms of anthraquinone dyes.
· Factors affecting bacterial anthraquinone dye degradation may include pH, temperature, external carbon and nitrogen sources, oxygen, and dye concentration and structure.
