Potable water availability is becoming increasingly challenging due to increasing level of global population and industrial revolution. The disproportionate use methylene blue (MB), particularly in applications, a growing concern its high resistance biodegradation propensity taint aquatic environments. In this study, we developed novel eco-friendly calcium oxide nanoparticles from eggshells fishbones (CaONPs-ES CaONPs-FB) decorated them on graphene (GO) surfaces. Both nanocomposites (CaONPs-ES@GO CaONPs-FB@GO) were characterized using state-art-instruments used for the removal MB aqueous solutions. transmission electron.

Recent Advances in Efficient Photocatalytic Degradation Approaches for Azo Dyes

Journal of Chemistry, Journal Year: 2023, Volume and Issue: 2023, P. 1 - 24

Published: Dec. 26, 2023

In recent decades, the textile industry has contributed to continuous pollution in environment. Synthetic dyes which are commonly found waste water azo, sulfur, anthraquinone, triphenylmethyl, indigoid, and phthalocyanine derivatives. These pollutants block light penetration bodies prevent photosynthesis activity, thereby affecting aquatic life. As an environmental crisis, several technologies have been explored control pollution. Among all techniques, photocatalysis process is considered as a green, simple, economical process. To improve photocatalytic researchers worldwide investigated various photocatalysts such metal oxides, ferrites, heterostructured nanocomposites. The major goal of this review article propose high-performing, cost-effective hybrid photocatalyst reported date for prospective azo dye pollutant remediation. This also aimed highlight challenges uncertainties associated with degradation

Highly Sustainable Dyes Adsorption in Wastewater Using Textile Filters Fabricated by UV Irradiation

Polymers, Journal Year: 2023, Volume and Issue: 16(1), P. 15 - 15

Published: Dec. 19, 2023

Vast amounts of dyeing wastewater released from the textile industry can not only cause water pollution but also have negative effects on human body, such as skin irritation and respiratory diseases. Dye adsorption technology is necessary for treatment discharged environmental improvement. However, to remove wastewater, more energy solvents are used fabricate adsorbents, or excessive filter out, resulting in pollution. Therefore, it develop a method filtering environmentally friendly manner by minimizing use energy. In this study, we modified surface substrate through UV irradiation create monomer capable facilely bonding with dyes. Employing photografting method, were able produce dye manner, solvent usage heat consumption required absorbent synthesis. At concentration 10%, fabricated exhibited removal efficiency 97.34% after 24 h, all without need pressure temperature increase. Moreover, displayed an capacity approximately 77.88 mg per 1 g material.
