Microporous carbon derived from waste plastics for efficient adsorption of tetracycline: Adsorption mechanism and application potentials
Scientists converted waste PET plastic bottles into a porous carbon material that can remove 100% of the antibiotic tetracycline from water. The material worked effectively across a wide range of water conditions and could be reused multiple times. This approach offers a double benefit: it repurposes plastic waste that would otherwise become microplastic pollution while also cleaning antibiotics from water, addressing two environmental threats at once.
Remoção de antibióticos da água por nanofiltração
This paper is not about microplastics. It evaluates nanofiltration membrane technology for removing antibiotics (tetracycline, norfloxacin, and sulfamethoxazole) from water, achieving up to 95% removal. While water treatment technology is broadly relevant to contaminant removal, this study focuses specifically on pharmaceutical contamination rather than microplastic pollution or exposure.

Researchers developed an advanced photocatalyst that degrades nearly 97% of tetracycline, a common antibiotic pollutant, in water within 180 minutes using light-activated chemical reactions. The system showed good stability for reuse and reduced the toxicity of breakdown products. While focused on antibiotic removal rather than microplastics, this water treatment technology is relevant because microplastics often carry adsorbed antibiotics, and removing both contaminants is important for safe drinking water.
Adsorption Capacity of Tetracycline in Solution by Cu-BTC@Carboxyl-Functionalized Carbon Nanotubes@Copper Alginate Composite Aerogel Beads
Researchers developed composite aerogel beads made from Cu-BTC metal-organic framework, carboxyl-functionalized carbon nanotubes, and copper alginate to adsorb tetracycline from sewage, systematically characterizing the adsorption performance and mechanisms of this nanomaterial composite for antibiotic removal from wastewater.

Researchers developed a new composite material that can break down nearly all tetracycline antibiotic pollution in water using visible light. While focused on antibiotic removal rather than microplastics, the technology is relevant because microplastics commonly carry absorbed antibiotics in water environments. Advanced treatment methods that remove antibiotics could also help address the broader problem of microplastics acting as carriers for harmful chemicals in drinking water sources.

The impact of chlorination on the tetracycline sorption behavior of microplastics in aqueous solution
Researchers found that chlorination, a common disinfection step in wastewater treatment, alters the surface chemistry of microplastics and changes their capacity to adsorb tetracycline antibiotics, with chlorinated microplastics showing modified sorption behavior that affects their role as antibiotic carriers.
Synthesis of invasive plant biochar catalyst with carbon nitride structure for peroxymonosulfate activation toward efficient ciprofloxacin degradation
Researchers created a new material from an invasive plant that, when combined with cobalt, could break down the common antibiotic ciprofloxacin in water within just 10 minutes with 98% efficiency across four reuse cycles. This "treat waste with waste" approach offers a promising low-cost tool for removing pharmaceutical pollutants from water supplies.

Adsorption of tetracycline on polyvinyl chloride microplastics in aqueous environments
This study found that PVC microplastics in water can absorb up to 93% of the antibiotic tetracycline under certain conditions. This means microplastics may act as carriers for antibiotics and other pollutants, potentially delivering harmful chemicals into drinking water and the food chain. The findings highlight how microplastics can make other environmental contaminants more dangerous to human health.
Combined pollution of tetracyclines and microplastics in the aquatic environment: Insights into the occurrence, interaction mechanisms and effects
This review examines how microplastics and tetracycline antibiotics interact in water environments, since microplastics can absorb and carry antibiotics on their surfaces. Factors like pH, heavy metals, and organic matter in water influence how tightly antibiotics bind to microplastics, and the combined pollution is more harmful to aquatic life than either pollutant alone. This is relevant to human health because these microplastic-antibiotic combinations can enter drinking water supplies and promote antibiotic resistance.
Effects of Polystyrene Microplastics on Multiple Tetracycline Removals by Ferrate
This study investigated how polystyrene microplastics affect the removal of antibiotics (tetracyclines) by ferrate water treatment. Fresh microplastics actually boosted antibiotic removal by nearly 30%, while weathered microplastics varied in their effect and heavily soaked microplastics reduced removal efficiency by up to 42%. These results show that microplastics can interfere with water treatment processes in complex ways, complicating the removal of pharmaceutical pollutants from drinking water sources.
Fe-Modified Sewage Sludge Biochar for Efficient Removal of Nanoplastics from Water: Mechanistic Insights and Multi-Pathway Adsorption Analysis
Scientists developed a new water filter material made from sewage sludge and iron that can remove 96% of tiny plastic particles (called nanoplastics) from water. These microscopic plastic bits are found everywhere in our water supply and may pose health risks, but this new filter works much better than existing methods. This research could lead to better ways to clean nanoplastics from our drinking water while also recycling waste materials.

Microplastics play a minor role in tetracycline sorption in the presence of dissolved organic matter
Researchers studied the sorption of the antibiotic tetracycline onto microplastics in the presence of dissolved organic matter, finding that dissolved organics competed strongly for binding sites on microplastics, meaning real-world conditions substantially reduce microplastic uptake of tetracycline.

Researchers found a way to repurpose waste sludge from microplastic removal processes by converting it into a nitrogen-doped carbon material that can break down the antibiotic tetracycline in water. The recycled material performed well across a wide pH range and worked primarily through a nonradical pathway to degrade the antibiotic. The study offers a dual benefit approach that addresses both microplastic waste management and antibiotic contamination in water systems.
