Recent Advances of Metal–Organic Framework for Heavy Metal Ions Adsorption

Langmuir, Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 13, 2024

Heavy metal ion wastewater is a pressing and inescapable issue that closely related to human health ecological security due its toxicity, carcinogenicity, the unmanageable property of this type wastewater. Metal–Organic Frameworks (MOFs) are class crystalline nanoporous materials with flexible designability controllability, showing great potential in field adsorption purification heavy metals In Perspective, we first discuss harm different ions briefly expound virtues MOFs for pollutant adsorption. Then, mainly summarize recent advances construction metal-based (Zr-based, Zn-based, Co-based, Al-based, etc.) their research progress Furthermore, various types MOF additives can often be effectively applied by functional modification or other composition. Additionally, several commonly used kinetics isotherm models also detailed help an in-depth understanding mechanism. Finally, challenges opportunities additionally discussed, review may provide new insight water applications.

Amorphous-dominated MgO hollow spheres enhanced fluoride adsorption: Mechanism analysis and machine learning prediction

The Journal of Chemical Physics, Journal Year: 2025, Volume and Issue: 162(1)

Published: Jan. 2, 2025

Amorphous-dominated magnesium oxide hollow spheres (A-MgO) were prepared using a spray-drying method in this study. These exhibited excellent sphericity, large specific surface areas, and abundant porosity. A-MgO outstanding fluoride adsorption properties, with maximum capacity of 260.4 mg/g. When the pH value was less than 8, removal percentage remained more 87.4%. Moreover, above 75% even after five application cycles. In addition, research revealed that SO42-, CO32-, PO43- exerted pronounced effect on removal, whereas coexisting ions such as Br-, Cl-, NO3-, HCO3- had minimal impact process. An in-depth analysis mechanism demonstrated process by involves various synergistic mechanisms, electrostatic adsorption, ion exchange, oxygen vacancy physical pore filling. To predict performance under complex conditions, high-performance machine learning model, GBDT-S, developed hyperparameter optimization. The R2 0.99 0.80 for training testing datasets, respectively, RMSE 3.26 3.89. Interpretative SHapley Additive exPlanations technology indicated reaction time, concentration, key factors influencing percentage.
