The removal of methylene blue from aqueous solutions by polyethylene microplastics: Modeling batch adsorption using random forest regression

Alexandria Engineering Journal, Journal Year: 2024, Volume and Issue: 95, P. 101 - 113

Published: April 1, 2024

In light of the extensive contamination water sources by microplastics, their substantial specific surface area makes them favorable candidates as adsorbents for simultaneous removal coexisting contaminants in wastewater. this regard, polyethylene microplastics were utilized to eliminate methylene blue dye from water. MB adsorption onto reached equilibrium just 30 min at pH 7. The better fit fractional power and Redlich-Peterson models on kinetic data, respectively, revealed that process is a chemisorption multilayer heterogeneous particles. reusability adsorbent was confirmed based promising outcomes observed after five cycles. results random forest regression exhibited an R2 97.55% correlation between model-computed measured amounts reduction. sensitivity analysis illustrated sorption highly influenced initial concentration mass. These show although may pose potential risks environments, can be simultaneously omit other pollutants aqueous solutions.

Fabrication of porous beta-cyclodextrin functionalized PVDF/Fe–MOF mixed matrix membrane for enhanced ciprofloxacin removal

npj Clean Water, Journal Year: 2024, Volume and Issue: 7(1)

Published: March 7, 2024

Abstract Herein, we demonstrate the synthesis of beta-cyclodextrin (β–CD) functionalized polyvinylidene fluoride (PVDF) and iron-based metal-organic framework (Fe–MOF) mixed matrix membrane (MMM) for enhanced removal ciprofloxacin (CIP) from water. The membranes were prepared using phase inversion technique with PVDF as polymer matrix, Fe–MOF filler, polyvinylpyrrolidone (PVP) porogen. optimized MMM 7% wt. exhibited excellent performance 87.6% efficiency. Moreover, maximum adsorption capacity was 6.43 mg g –1 . β–CD functionalization improved hydrophilicity by water contact angle (WCA) analysis (WCA = 55°). Furthermore, can be attributed to large specific surface area (682.5 m 2 ), high porosity (77%), average pore diameter (395 nm) membrane. inclusion PVP (1% wt.) porous nature and, consequently, CIP. Notably, hydrophilic macroporous showed good reusability over 70% efficiency after five sequential adsorption–desorption cycles. insights this study suggest that PMC–7 an candidate remediation organic contaminants aquatic environments.
