Removal of microplastics by algal biomass from aqueous solutions: performance, optimization, and modeling

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Jan. 2, 2025

Microplastics (MPs) are emerging pollutants that pose significant risks to ecosystems due their inherent toxicity, capacity accumulate various pollutants, and potential for synergistic impacts. Given these concerns, the focus of this research is on critical need effective MPs removal from aquatic environments. Using BBD method, study aimed identify key parameters affecting by algal biomass aqueous solutions. The investigation specifically analyzed effects varying initial PS concentrations (100 900 mg/L), pH values (4 10), reaction durations (20 40 min), C. vulgaris dosages (50 400 mg/L). Data analysis indicated QM best described experimental findings, leading identification optimal conditions removal: a 7.5, time 31.90 min, dosage 274.05 mg/L, level 789.37 mg/L. Under conditions, achieved maximum efficiency 73.01% PS. These outcomes demonstrate in efficiently removing water. Furthermore, using algae as green, eco-friendly alternative conventional chemical coagulants offers practical sustainable approach addressing pollution our water systems.

Adsorption of tetracycline on polyvinyl chloride microplastics in aqueous environments

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: Oct. 20, 2023

Abstract Microplastics (MPs), as carriers of organic pollutants in the environment, have become a growing public concern recent years. Tetracycline (TTC) is an antibiotic that can be absorbed by MPs and harmful effect on human health. Therefore, this study was conducted with aim investigating adsorption rate TTC onto polyvinyl chloride (PVC) MPs. In addition, mechanism process studied using isothermal, kinetic, thermodynamic models. For purpose, experimental runs Box-Behnken model were designed to investigate main research parameters, including PVC dose (0.5–2 g/L), reaction time (5–55 min), initial concentration (5–15 mg/L), pH (4–10). Based findings, highest (93.23%) obtained at 10, contact 55 min, adsorbent 1.25 g/L, 10 mg/L. The found followed pseudo-second-order Langmuir Thermodynamic data indicated spontaneous, exothermic, physical. Increasing ion decreased adsorption, distilled water had while municipal wastewater lowest adsorption. These findings provide valuable insights into behavior pollutants, underscoring importance conducting additional implementing measures mitigate their detrimental effects health environment.

Aging effect on the adsorption behavior of microfibers obtained from cigarette butts in aqueous solutions

Applied Water Science, Journal Year: 2024, Volume and Issue: 14(2)

Published: Jan. 28, 2024

Abstract The issue of cigarette butts is an environmental crisis that has affected the world. Despite their small size, CBs are one most common types solid waste found in public places, particularly coastal areas. aim this study was to investigate adsorption behavior microfibers obtained from on tetracycline before and after aging. 1 g added 50 mL distilled water stirred at 220 rpm for 2 h, then filtered through Whatman 0.45 µm filter paper, resulting MFs were dried 60 °C 24 h. To simulate aging, subjected ultrasonic treatment a frequency 80 Hz power 70 W 4 aged fresh investigated using solutions containing TTC range 5–20 mg/L. This showed ultrasonically had greater tendency adsorb than due increased surface area changes chemistry. It can be concluded as age increases, they more concentration pollutants. lead contamination presence contaminants.
