Summary: This paper studies the adsorption behavior of heavy metal ions on limonitic laterite and describes the mechanism of Pb2+ and Cd2+ hydrate adsorption in detail using density functional theory (DFT) calculations. The results show that the removal ratios of Pb2+ and Cd2+ by laterite are 99.1% and 86.17%, respectively, which are much higher than the removal efficiencies of Pb2+ and Cd2+ by synthetic goethite. Isothermal adsorption and kinetic analysis indicate that Pb2+ and Cd2+ are chemically adsorbed on laterite as a single molecular layer. Further DFT analysis reveals that Pb2+ hydrate exhibits bidentate adsorption on the goethite (010) surface, while the Cd2+ hydrate displays monodentate adsorption. Partial density of states (PDOS) and differential charge density analyses suggest that the Pb6d orbital hybridizes with the O1s orbital and the Pb6s orbital with the O2p orbital, forming the Pb-O bond. The Cd5s orbital hybridizes with the O2p orbital, forming the Cd-O bond. Both Pb2+ and Cd2+ undergo stable chemical absorption on the goethite (010) surface.

Summary: Due to its irreversible toxicity and harm to human health, lead contamination has attracted a lot of attention. Therefore, the development of low-cost and high-performance removal methods has become a popular issue. In this study, a novel metal-organic framework (AMO-MOF) was developed for the selective adsorption of Pb(II) from water. AMO-MOF inherits the structural characteristics of mesoporous materials and has a specific surface area of 255.251 m2/g. The adsorption reached equilibrium at 180 min, and the maximum adsorption capacity of AMO-MOF for Pb(II) was 472.73 mg/g. The adsorption mechanism mainly involves the chelation and electrostatic interaction of N and O-containing functional groups on the adsorbent with Pb(II). The excellent adsorption performance of AMO-MOF for Pb(II) suggests its great potential for practical environmental remediation.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
