Evaluation of Fenton, Photo-Fenton and Fenton-like Processes in Degradation of PE, PP, and PVC Microplastics

Water, Journal Year: 2024, Volume and Issue: 16(5), P. 673 - 673

Published: Feb. 25, 2024

The global problem of microplastics in the environment is “inspiring” scientists to find environmentally friendly and economically viable methods remove these pollutants from environment. Advanced oxidation processes are among most promising methods. In this work, potential Fenton, photo-Fenton, Fenton-like for degradation low-density polyethylene (LDPE), polypropylene (PP), poly(vinyl chloride) (PVC) water suspensions was investigated. influence three parameters on efficiency process tested: pH medium (3–7), mass added iron (10–50 times less than microplastics), H2O2 (5–25 more iron). effectiveness treatment monitored by FTIR-ATR spectroscopy. After 60-min treatments, PP microparticles were found be insensitive. Fenton PVC photo-Fenton LDPE PVC, changes FTIR spectra related observed. cases, optimized. It that a low (3) high (optimal values 1/12 1/10 respectively) favored all three. concentrations (25 higher iron), while significantly lower (11 15 treatment, respectively), suggesting scavenging activity occurs.

The problem of polyethylene waste – recent attempts for its mitigation

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 892, P. 164629 - 164629

Published: June 5, 2023

For the past two decades, with increase in plastic consumption came a rise waste, bulk of it ending up landfills, incinerated, recycled or leaking into environment, especially aquatic ecosystems. Plastic waste poses significant environmental threat and wealth issue due to its non-biodegradability recalcitrant nature. Polyethylene (PE) remains one major utilized polymers different applications amid all other types because low production costs, simplistic nature prone be modified historically predominant researched material. Since common methods for disposal are troubled by limitations, there is growing need more appropriate environment friendly alternatives. This study highlights several ways that can used assist PE (bio)degradation mitigate impact. Biodegradation (microbiological activity driven) photodegradation (radiation most promising control. The shape material (powder, film, particles, etc.), composition medium, additives pH, temperature incubation exposure times contribute degradation efficiency. Moreover, radiation pretreatment enhance biodegradability PE, providing approach fighting pollution. paper relates results regarding studies followed weight loss analysis, surface morphology changes, oxidation degree (for photodegradation) mechanical properties assessment. All combined strategies very minimize polyethylene However, still long way go through. kinetics currently available biotic abiotic processes, complete mineralization thoroughly unseen.
