Catalytic and Physicochemical Evaluation of a TiO2/ZnO/Laccase Biocatalytic System: Application in the Decolorization of Azo and Anthraquinone Dyes
Researchers developed a biocatalytic system combining titanium dioxide, zinc oxide, and the enzyme laccase to break down textile dyes in wastewater. The system successfully decolorized two types of synthetic dyes used in fabric manufacturing. While not directly about microplastics, synthetic dye wastewater from textiles also carries microfibers, and treatments that address both problems together are environmentally valuable.

Removal of Azo Dyes from Aqueous Effluent Using Bio-Based Activated Carbons: Toxicity Aspects and Environmental Impact
This review discusses the toxic effects of azo dyes, widely used in textile manufacturing, and methods for removing them from wastewater using activated carbon. While not directly about microplastics, the research connects to microplastic concerns because synthetic textile fibers that shed as microplastics often contain residual azo dyes. When these microfibers enter waterways, they can release dye chemicals that are known to be carcinogenic and mutagenic, adding a chemical dimension to microplastic pollution.

Ozone-mediated breakdown of microplastics in aqueous environments
Researchers examined how ozone-based advanced oxidation processes break down microplastics in water treatment settings. They found that while ozone can degrade certain plastics, the effectiveness varies depending on particle size, polymer type, and treatment conditions, and the process may generate nanoplastic byproducts. The study highlights both the promise and limitations of ozone treatment as a strategy for removing microplastics from wastewater.
The effect of Ozonation on the chemical structure of microplastics
Ozone treatment of microplastics in water caused oxidative changes to polymer surfaces including carbonyl group formation and surface cracking, which altered hydrophobicity and potentially increased the capacity of treated particles to adsorb contaminants, suggesting that ozonation in water treatment may chemically transform rather than eliminate microplastic hazards.

Effects of Ozonation and Anaerobic Digestion on the Physicochemical Properties of Low-Density Polyethylene, Polypropylene, and Polyamide 66 Microplastics
Scientists tested whether ozone treatment could help break down tiny plastic particles (called microplastics) that build up in wastewater treatment plants. The ozone changed the surface chemistry of the plastics and made them less stable, but didn't actually reduce the amount of plastic particles. This research is important because microplastics from wastewater can end up in our food and water, so finding better ways to remove or break them down could help protect human health.

While focused on cleaning up dyes, drugs, and pesticides, the technology is relevant to microplastics because similar photocatalytic approaches are being explored to degrade plastic particles in water. Improving water treatment technologies like these could help reduce human exposure to the cocktail of pollutants, including microplastics, found in water supplies.
