Cationic Metal–Organic Framework Nanoparticles Based on UiO-66 for Effective ReO₄^– Capture

ACS Applied Nano Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 9, 2025

ReO4– as a hazardous waste severely threatens environmental safety and human health. The high-efficiency adsorbent for the removal of is immense interest but still faces challenges. Herein, we established cationic metal–organic framework nanoparticles by an amino protonation strategy. Based on facile green method, first introduced dense groups (6.59 mmol/g) in UiO-66 situ to prepare UiO-66-(NH2)2, during which acetic acid modulator was applied construct defects. Subsequently, UiO-66-(NH2)2 acidified UiO-66-(NH3+Cl–)2. Notably, this exhibits high adsorption capacity 590.2 mg g–1 short equilibrium time 240 min ReO4–. Besides, excellent chemical stability reusability endow UiO-66-(NH3+Cl–)2 with promising potential practical applications. Experimental characterization density functional theory (DFT) calculations suggest that electrostatic interaction, ion exchange, coordination interaction jointly contribute effective Thus, work provides highly efficient nanoparticle and, importantly, proposes feasible strategy constructing adsorbents.

Published: Feb. 19, 2025

Mercaptopropionyl wheat straw (MPWS) was prepared as an adsorbent by modifying with mercaptopropionyl groups, and the ability of MPWS for removal Ni(II) from aqueous solution examined. The using identified through investigating impacts dosage, adsorption temperature, time. Different models isotherm kinetics were utilized to fit experimental results elucidate mechanism Ni(II). Environmental interference factors, including initial concentration, pH value, inorganic matters, organic matters in wastewater, examined evaluate antienvironmental disturbance capability during adsorption. A rate high 99.02% achieved at 6.0 temperature 30 °C a contact time 100 min. exhibited excellent alignment both pseudo-second-order kinetic model, Freundlich isothermal Redlich–Peterson Hill model. Furthermore, coexisting substances environment could inhibit process MPWS; however, this inhibition be mitigated or eliminated increasing amount absorbent MPWS. Overall, displays remarkable resistance against environmental its application removing wastewater.

Efficiency of heat-treated sepiolite in the adsorption of Cd, Zn, and Co from aqueous solutions: A low-cost approach for wastewater treatment

Deleted Journal, Journal Year: 2024, Volume and Issue: 2(2), P. 1562 - 1562

Published: Sept. 30, 2024

This study investigated the adsorption of Cd, Co, and Zn ions onto unmodified heat-treated sepiolite, focusing on effect contact time, initial pH, heat pretreatments. Kinetic experiments were conducted in triplicate, equilibrium indicated that Co2+ had highest preference, followed by Zn2+ Cd2+. The efficiency for significantly increased with higher whereas Cd2+ showed optimal at lower pH levels. Heat-treated sepiolite 250 ℃ exhibited a surface area capacity comparison 150 ℃-treated which importance pretreatment. pseudo-second-order kinetic model better described process, it was confirmed chemisorption as rate-limiting step. By increasing rates enhanced, achieved within 480 min all systems. Higher solute concentrations led to an increase processes, Co consistently showing competitive multi-ionic solutions. Adsorption percentages varied thermal treatment, indicating these parameters optimizing sepiolite’s heavy metal removal.
