ClearRemoção 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.

Assessment of Molecularly Imprinted Polymers as Selective Solid-Phase Extraction Sorbents for the Detection of Cloxacillin in Drinking and River Water
Not relevant to microplastics — this paper develops a molecularly imprinted polymer method for detecting the antibiotic cloxacillin in drinking water, with no connection to plastic particles.
The Photocatalytic Degradation of Enrofloxacin Using an Ecofriendly Natural Iron Mineral: The Relationship Between the Degradation Routes, Generated Byproducts, and Antimicrobial Activity of Treated Solutions
This paper is not relevant to microplastics research; it investigates the photocatalytic degradation of the antibiotic enrofloxacin in water using a natural iron mineral, focusing on pharmaceutical contamination rather than plastic particles.
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.
Removal of Antibiotics by Biochars: A Critical Review
This review analyzes how biochars, which are carbon-rich materials made from organic waste, can remove antibiotics from water. While not directly about microplastics, the research is relevant because both antibiotics and microplastics are emerging water contaminants, and microplastics can carry antibiotic residues that promote drug-resistant bacteria. Better water treatment methods that address multiple contaminants could help reduce human exposure to both pollutants.
Mechanistic insights to sorptive removal of four sulfonamide antibiotics from water using magnetite-functionalized biochar
This paper is not about microplastics. It investigates how magnetite-functionalized biochar removes sulfonamide antibiotics from water, finding that hydrogen bonding is the primary mechanism of adsorption and that the material's oxygen-containing surface groups drive removal efficiency. The study focuses on antibiotic water contamination remediation rather than microplastic pollution.
Aged microplastics enhance their interaction with ciprofloxacin and joint toxicity on Escherichia coli
Researchers found that aged microplastics showed enhanced adsorption of the antibiotic ciprofloxacin compared to pristine particles, and that their combined exposure produced greater toxicity to E. coli at the molecular level than either pollutant alone.
Sustainable removal of contaminants of emerging concern from wastewater by the living membrane bioreactor: effect of the co-occurrence of microplastics and antibiotics
Researchers investigated a living membrane bioreactor (LMBR) for removing the antibiotic ofloxacin and oxidized polyethylene microplastics from urban wastewater, finding that the biological membrane effectively retained both contaminants of emerging concern and that microplastics acted as antibiotic carriers, with their co-presence influencing overall removal efficiency.
Optimizing composite microplastics for antibiotics removal in water: An eco-friendly solution
Researchers investigated the adsorption of antibiotics ciprofloxacin and flucloxacillin onto PET and HDPE microplastics, characterizing the particles via FTIR, SEM, and EDX and fitting isotherm models to show that microplastics can serve as carriers of antibiotic pollutants in aquatic environments.
Decontamination of levofloxacin from water using a novel chitosan–walnut shells composite: linear, nonlinear, and optimization modeling

Understanding and characteristics of coagulation removal of composite pollution of microplastic and norfloxacin during water treatment
The coagulation removal of microplastics and the antibiotic norfloxacin together was studied in a water treatment context, finding that the presence of microplastics altered the coagulation behavior of norfloxacin and that their combined removal was less effective than treating either pollutant alone. The results highlight composite pollution as a challenge for conventional water treatment processes.
Norfloxacin removal efficiency by a carbon filtration column under the influence of nanoplastics: mechanistic analysis and prediction model
Researchers designed experiments to examine how nanoplastics influence norfloxacin removal efficiency in activated carbon filtration columns used in drinking water treatment, developing a mechanistic analysis and predictive model for antibiotic leakage risk when nanoplastics act as carriers in the filtration system.
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.
Removal of sulfamethoxazole using Fe-Mn biochar filtration columns: Influence of co-existing polystyrene microplastics
Researchers investigated how polystyrene microplastics affect the removal of the antibiotic sulfamethoxazole using iron-manganese modified biochar filtration columns. They found that the presence of microplastics significantly reduced antibiotic retention due to competitive sorption, with the effect varying depending on water pH. The study highlights that co-occurring microplastics in wastewater can interfere with contaminant removal systems, potentially allowing more antibiotics to pass through treatment processes.
Architectural design of 2D covalent organic frameworks (COFs) for pharmaceutical pollutant removal
Researchers used computer simulations to design special porous materials called covalent organic frameworks that can trap and remove pharmaceutical pollutants like antibiotics from wastewater.
