Chemical Engineering Journal Advances, Journal Year: 2023, Volume and Issue: 16, P. 100529 - 100529

Published: June 26, 2023

Microplastics, which are small plastic particles, have become a growing environmental concern due to their prevalence in aquatic and terrestrial environments. They persist for decades potentially centuries resistance degradation can harm organisms release toxic chemicals. There has been increasing interest developing methods removal from the environment, particularly water. Catalytic processes shown promise as potential method microplastic elimination, including biological methods, advanced oxidation processes, hydrolysis. This review article focuses on recent advances catalytic of microplastics water, various types catalysts applications. It also discusses be integrated into real-world water treatment systems microplastics. The highlights challenges opportunities associated with environment aims contribute development more effective sustainable addressing this issue. Future research should focus hybrid catalyst that combine strengths multiple improved efficiency effectiveness. Additionally, explore use natural materials may offer environmentally friendly options. Collaboration between scientists, engineers, policymakers, public will critical implementation these systems. elimination requires multifaceted approach, continued collaboration necessary develop protect health our communities.

Photocatalytic degradation of different types of microplastics by TiOx/ZnO tetrapod photocatalysts

Heliyon, Journal Year: 2023, Volume and Issue: 9(11), P. e22562 - e22562

Published: Nov. 1, 2023

We investigated the use of titania coated ZnO tetrapods for photocatalytic degradation two common types microplastics, namely polyethylene (PE) microparticles and polyester (PES) microfibers. found that plastics morphology affects rate degradation, electron scavengers is needed to maintain reactivity photocatalysts over a prolonged period time. Complete mass loss PE PES achieved under UV illumination 480 h 624 h, respectively. In addition pristine environmental microplastics sample (consisting primarily polypropylene) was also demonstrated, though in this case longer time (∼816 h) achieve complete samples.

Potential of Advanced Oxidation as Pretreatment for Microplastics Biodegradation

Separations, Journal Year: 2023, Volume and Issue: 10(2), P. 132 - 132

Published: Feb. 15, 2023

In the last two decades, microplastics (MP) have been identified as an emerging environmental pollutant. Due to their small size, MP particles may easily enter food chain, where they can adverse effects on organisms and environment in general. The common methods for removal of pollutants from are not fully effective elimination MP; thus, it is necessary find a more suitable treatment method(s). Among various approaches tested, biodegradation by far most environmentally friendly economically acceptable remediation approach. However, has serious drawbacks, generally related rather low rate often insufficient efficiency. Therefore, would be beneficial use some less economical but efficient pretreatment prior biodegradation. Such primarily serve increase roughness hydrophilicity surface MP, making susceptible bioassimilation. This review focuses advanced oxidation processes (AOPs) that enhance particles. It considers six commonly used plastic polymers, namely: polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyethylene terephthalate polyurethane. highlights with high potential selected presents benefits AOP provide

The extensive production and application of plastic in recent decades has resulted the presence microplastics (MPs) different water bodies. Considered as contaminants emerging concern (CECs), MPs are accessible to a wide range organisms can act vectors for transport other persistent organic pollutants. existing technologies remove from wastewaters prevent their intrusion nature, still present several limitations, resulting an urgent need develop novel, fast, cost-effective greener alternatives. In this work, magnetophoretic capture by assembly with magnetic nanoparticles through either electrostatic interactions or molecular forces is investigated. For experimental assessment, were synthesized hydrothermal coprecipitation solvothermal decomposition methods, while polyethylene (PE) microspheres selected model microplastic As noteworthy novelty, thermal particles functionalized amino groups sodium alginate (SA), respectively, modification surface properties enhanced MPs. After preliminary experiments, concentration 1.3 g L-1 contact time 20 min between MPs, operating conditions assess influence functional on performance. variables process was also evaluated, including synthesis method, pH medium, varied 4–8, constituents that may be Results demonstrated types polar make them interact towards attraction forces, considerably enhancing performance bare nanoparticles. This work represents step forward development new reliable techniques environmentally friendly polluted waters.
