Summary: Inordinate levels of heavy metals in water sources pose serious environmental and public health risks, but adsorption is an efficient, low-cost, and easy-to-operate technique for their removal. Blast furnace slag has been found to be a cheap sorbent that effectively removes Co2+ and Pb2+ ions from water. The adsorption process is influenced by factors such as pH, contact time, adsorbent dose, temperature, and initial ions concentration. The main adsorption mechanism between the slag and metal ions is ion exchange. Nonmodified BFS treatment shows great potential as a cost-effective adsorbent for water pollution treatment in terms of economics and scalability.

Summary: The presence of nanoparticles in drinking water raises concerns about their potential risks to human health and the efficacy of water treatment plants in removing them. This study examines the efficiency of granular activated carbon (GAC) in removing CeO2 nanoparticles. The results show that GAC has a good affinity for nanoparticles, with higher adsorption capacity and removal efficiency in lake water compared to ultrapure water. The adsorption mechanism is mainly controlled by electrostatic attractions, and mass transfer processes play a role in the removal of nanoparticles in lake water.

Summary: EAF slag aggregate, a waste by-product of the steel industry, has shown great potential for phosphorus removal. This study evaluated the performance of using EAF slag aggregate as an adsorbent for phosphorus removal and identified its removal capacity. Batch tests showed that the highest phosphorus removal capacity can be achieved at pH 12. The adsorption kinetics can be described by a pseudo-second-order kinetic equation and the best fitted isothermal adsorption model is the Freundlich model. A continuous flow column experiment demonstrated that EAF slag could efficiently remove phosphorus with a removal efficiency greater than 95%.

Summary: This study investigated the adsorption of soil organic phosphorus by lanthanum modified biochar, traditional gypsum, and zeolite using phytic acid. The results showed that modified biochar had the strongest affinity for phytate phosphorus and the ability to store phosphorus, fitting well with Langmuir isotherm and pseudo-second-order kinetic equation. Overall, the combination of modified biochar and soil phytate phosphorus can provide a good theoretical basis for reducing the loss of soil organic phosphorus.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

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.
