Advanced industrialization requires an enormous amount of water, dyes, and chemicals, it continuously releases toxic effluents into the environment water bodies. In textile, paper, leather, other industries, dyes are compounds being used to provide color substances. Among all utilized in dyeing sector, azo contribute about 60 % dyestuffs globally. Synthetic harm aesthetic qualities resources by elevating COD (Chemical oxygen demand) BOD (Biological demand), substances, turbidity, hindering photosynthesis, stifling plant development, contaminating food chain, inducing recalcitrance, accumulation, effectively stimulating toxicity, carcinogenicity, as well mutagenicity. To minimize negative impacts on surroundings, people, natural bodies, wastewater comprising dye pollutants must be removed through eco-friendly technology. As a result, treatment these textile is required before they eliminated surroundings. Physical, chemical, physio-chemical, biological methods among those for treating wastewater. Biological methods, such with bacteria, bacterial enzymes, fungi, plants, were due their environment-friendly cost-effective method. The classification degradation mechanism bacteria addressed this paper.

Abstract In the current arena, new-generation functional nanomaterials are key players for smart solutions and applications including environmental decontamination of pollutants. Among plethora nanomaterials, graphene-based nanocomposites in driving seat surpassing their counterparts due to unique physicochemical characteristics superior surface chemistry. The purpose present research was synthesize characterize magnetite iron oxide/reduced graphene oxide (FeNPs/rGO) via a green approach test its application degradation methylene blue. modified Hummer's protocol adopted (GO) through chemical exfoliation using graphitic route. Leaf extract Azadirachta indica used as reducing agent reduce GO into reduced (rGO). Then, deposition leaf extract, nanocomposite comprising oxides i.e., FeNPs/rGO synthesized. During synthesis functionalized FeNPs/rGO, acted reducing, capping, stabilizing agent. final synthesized materials were characterized analyzed an array techniques such scanning electron microscopy (SEM)-energy dispersive X-ray microanalysis (EDX), Fourier transform infrared spectroscopy (FT-IR), diffraction analysis, UV–visible spectrophotometry. spectrum evaluate optical band gap. Using FT-IR spectrum, groupings identified nanocomposites. morphology elemental analysis process investigated SEM–EDX. GO, rGO, FeNPs, showed maximum absorption at 232, 265, 395, 405 nm, respectively. FTIR different groups (OH, COOH, C=O), C–O–C) modifying material surfaces. Based on Debye Sherrer's equation, mean calculated particle size all < 100 nm (GO = 60–80, rGO 90–95, FeNPs 70–90, Fe/GO 40–60, Fe/rGO 80–85 nm). Graphene-based displayed rough surfaces with clustered spherical shapes EDX confirmed presence both oxygen produced synthetic degraded approximately 74% results, it is plausible conclude that can also be potential photocatalyst degrader other dye pollutants lower
