Enhancement of Pb(II) Adsorption by Aged Microplastics in the Presence of Microalgae: Kinetic and Mechanistic

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Апрель 1, 2025

This study investigated the effects of different aging treatments (UV light, potassium permanganate, and sodium hydroxide treatments) on adsorption lead (Pb(II)) by PET microplastics, as well impact Microcystis aeruginosa microplastics. The results indicated that significantly affected capacity which could be attributed to increased functional groups surface porosity during process. Kinetic analysis revealed Pb(II) follows a pseudo-second-order model, suggested process is mainly controlled chemical adsorption. Intraparticle diffusion further elucidated migration mechanism within On other hand, presence enhanced As concentration microalgae increases, promoting effect microplastics gradually strengthens, with extracellular polymeric substances (EPS) secreted playing key role in facilitating These findings strengthen carriers heavy metal aggravate risk pollution aquatic ecological environment.

Lead ions removal from water by tartaric acid modified biochar materials: Equilibrium, kinetic studies and mechanism

Desalination and Water Treatment, Год журнала: 2024, Номер 320, С. 100601 - 100601

Опубликована: Июль 25, 2024

This study endeavors to optimize the resource utilization of waste sludge while mitigating environmental risks associated with Pb2+ contamination. Tartaric acid was used as an activator in production modified biochar (MBC-TA, PBC-TA) extracted from municipal and pharmaceutical a means enhance functional groups on surface its adsorption properties. The research systematically examined various influential factors affecting adsorption, namely adsorbent dosage, reaction time, pH. physicochemical properties were evaluated utilizing scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) analysis, point zero charge (pHPZC) analysis. results revealed that modifications significantly impacted efficiency. kinetic model showed by two sludge-derived more consistent pseudo-secondary model, mainly chemisorption. isotherm models fitted analyzed, it found Langmuir adsorbents behavior, relied monomolecular layer capacity tartaric acid-modified MBC-TA PBC-TA increased 22.58 mg/g 22.86 mg/g, respectively. finding underscores efficacy modification augmenting pollutant removal capabilities materials.

CuAl-LDH Modified with Filamentous Macroalgae for Anionic Dyes Removal: A Study on Selectivity, Adsorption Efficiency, and Regeneration

BULLETIN OF CHEMICAL REACTION ENGINEERING AND CATALYSIS, Год журнала: 2024, Номер 19(4), С. 560 - 572

Опубликована: Окт. 30, 2024

Continuous modifications of Layered Double Hydroxides (LDH) materials are essential to enhance their structural stability and improve capacity for pollutant adsorption, addressing the need more effective remediation strategies in environmental applications. This research study has proposed preparation CuAl-LDH supported filamentous macroalgae Spirogyra sp. (CuAl-LDH/SA) via coprecipitation hydrothermal methods. The prepared CuAl-LDH/SA composites were investigated adsorption direct yellow 12 (DY) remazol red (RR) dyes batch mode experiments. structure morphology identified by X-ray Diffraction (XRD), Fourier Transform Infra Red (FT-IR), (Brunauer-Emmett-Teller) BET surface area, Thermogravimetry / Differential Thermal Analyzer (TG/DTA), Scanning Electron Microscope (SEM). For process, effects initial pH, contact time, concentration, temperature, selectivity, adsorbent regeneration, as well kinetics, isotherms, thermodynamics studied. selectivity test resulted RR dye being selective compared DY. maximum capacities 72.464 mg/g (pH = 2, 150 min, 303 K). can be regenerated 4 cycles with a percent removal 29.32%. process followed intraparticle diffusion kinetics model Langmuir isotherm. Thermodynamic studies showed that using was endothermic spontaneous. results this indicate composite material shows potential anionic from aqueous solutions.
