“…Since most dyes are synthetic, they are more persistent and challenging to degrade due to their complex aromatic molecular structure. Chromophores and auxochromes are the two categories of chemicals that make up a dye (Vats et al, 2022) [7] . In this review, the methylene blue dye's structure is emphasised, and its effects on the environment and human health are also covered.…”

The presence of dyes in wastewater and water resources is one topic that is getting attention on a global scale. In the present decade, dye-based categories have seen vast development due to the rising need for garments by the increase in population. Mostly used dye in textiles is Methylene blue, which gives dye outflow contamination. It is dangerous and very risky for the surroundings. There are countless sources of methylene blue dye and their adequate medical care methods are inscribed in this present review. The multifunctional ZnO nanomaterial is more effective as a semiconducting photocatalyst than other materials because of its low cost, eco-friendliness, structure-dependent characteristics, and complete mineralization of pollutants. Among nanoparticles photocatalysts, ZnO have shown major capability for photoactive methylene blue deterioration. These metal oxides nanoparticles are the best perfect matter for abolishment of water contaminants, like materials are connected to the attributes of purity, malleability, adaptability, productivity and are highly reactive. The structure of methylene blue dye is highlighted and health impact as well as their effect environment are also discussed. Taking account of all these crucial aspects, the recent advances for remedy of cationic dyes methylene blue by applying ZnO nano is spotlighted in this current review.

“…Dyes at relatively low concentrations can significantly increase the chromaticity of water bodies, diminishing water transparency and self-purification. The presence of dyes in aquatic ecosystems will hinder light penetration into deeper layers, reducing photosynthetic processes in aquatic organisms, deteriorating the water quality, and posing a direct threat to the survival of aquatic organisms [23,24]. The discharge of dye-contaminated wastewater into environments such as lakes and rivers can cause severe damage to aquatic organisms, potentially inducing mutagenic and teratogenic effects [24].…”

To fully harness the potential of laccase in the efficient decolorization and detoxification of single and mixed dyes with diverse chemical structures, we carried out a systematic study on the decolorization and detoxification of single and mixed dyes using a crude laccase preparation obtained from a white-rot fungus strain, Pleurotus eryngii. The crude laccase preparation showed efficient decolorization of azo, anthraquinone, triphenylmethane, and indigo dyes, and the reaction rate constants followed the order Remazol Brilliant Blue R > Bromophenol blue > Indigo carmine > New Coccine > Reactive Blue 4 > Reactive Black 5 > Acid Orange 7 > Methyl green. This laccase preparation exhibited notable tolerance to SO42− salts such as MnSO4, MgSO4, ZnSO4, Na2SO4, K2SO4, and CdSO4 during the decolorization of various types of dyes, but was significantly inhibited by Cl− salts. Additionally, this laccase preparation demonstrated strong tolerance to some organic solvents such as glycerol, ethylene glycol, propanediol, and butanediol. The crude laccase preparation demonstrated the efficient decolorization of dye mixtures, including azo + azo, azo + anthraquinone, azo + triphenylmethane, anthraquinone + indigo, anthraquinone + triphenylmethane, and indigo + triphenylmethane dyes. The decolorization kinetics of mixed dyes provided preliminary insight into the interactions between dyes in the decolorization process of mixed dyes, and the underlying reasons and mechanisms were discussed. Importantly, the crude laccase from Pleurotus eryngii showed efficient repeated-batch decolorization of single-, two-, and four-dye mixtures. This crude laccase demonstrated high stability and reusability in repeated-batch decolorization. Furthermore, this crude laccase was efficient in the detoxification of different types of single dyes and mixed dyes containing different types of dyes, and the phytotoxicity of decolorized dyes (single and mixed dyes) was significantly reduced. The crude laccase efficiently eliminated phytotoxicity associated with single and mixed dyes. Consequently, the crude laccase from Pleurotus eryngii offers significant potential for practical applications in the efficient decolorization and management of single and mixed dye pollutants with different chemical structures.

Congo red (CR) dye, due to its structural stability and non-degradable nature, is hazardous for humans and the aquatic environment. Among various methods used for degradation of CR, photocatalysis have been widely reported as a cost effective and environment-friendly method. Besides, extensive studies have been carried out regarding the use of nanomaterial-based photocatalyst for degradation of CR. This review describes the basics of photocatalysis along with the factors affecting the process, mechanism, and kinetics in detail. Additionally, literature related to synthetic and bio-based stabilizing mediums in photocatalytic assemblies have been arranged in a systematic manner. Advanced hybrid materials, i.e., metal–organic frameworks (MOFs) have also been described briefly. Future directions are discussed to address existing shortcomings in this field and also to expand research in this area.
