Summary: This study investigated the adsorptive removal of phenanthrene from synthetic soil washing effluent using activated carbon prepared from waste walnut shells. The effects of activated carbon dosage, Tween 80 concentration, and adsorption time on phenanthrene removal were studied using Box-Behnken statistical experiment design and response surface methodology. The results showed that the activated carbon dosage and adsorption time had a positive effect on phenanthrene removal, while the Tween 80 concentration had a negative effect.

Summary: This study evaluated the adsorption of fluoride using two low-cost adsorbents: palm shell activated carbon and chitosan of prawn shells. The highest removal efficiencies of fluoride by the adsorbents were 46% and 55% at pH 2 and 7, respectively. The contrasting behavior of the two adsorbents in relation to pH is attributed to the surface charge associated with surface functional groups identified by FTIR. Adsorption kinetics results fitted well into the pseudo-second-order kinetics model, suggesting a chemisorption mechanism of fluoride removal.

Summary: This study developed a highly efficient and low-cost activated carbon (BAC-600) derived from bagasse, which was used for the removal of sulfamethoxazole (SMZ) from water. The adsorption conditions were optimized using response surface methodology (RSM) with a Box-Behnken design (BBD). BAC-600 exhibited excellent adsorption performance, fitting well with the pseudo-second-order model. The adsorption mechanism of SMZ on BAC-600 involved hydrogen bonding, electrostatic interaction, and p-p interaction. This research provides a potential solution for eliminating environmental pollution caused by antibiotics in water.

Summary: This study systematically evaluated the concurrent adsorption of humic acid (HA) and hexavalent chromium (Cr(VI)) by powdered activated carbon (PAC) in water. It was found that the presence of humic acid significantly enhanced the adsorption of both HA and Cr(VI). The promotion effect of humic acid on Cr(VI) removal was found to decrease with increasing pH. The cooperative adsorption mechanism was attributed to the formation of Cr(VI)-HA and Cr(III)-HA complexes that were readily adsorbed on the PAC surfaces.

Summary: Activated carbons prepared from cashew nut shells by chemical activation with phosphoric acid were tested for the removal of acetaminophen. It was found that an increase in carbonization temperature resulted in increased pore volume and decreased amount of surface functional groups. The involvement of surface functional groups in the removal of acetaminophen was indicated to occur either via hydrogen bonding or by acid hydrolysis, with the carbon obtained at 600 degrees C exhibiting the highest adsorption capacity.

Summary: Perchlorate, a strong oxidizer, is an emerging contaminant that has gained attention due to its occurrence, reactive nature, and persistence in various environments. It is used in industries such as missile fuel and fertilizers. Ingesting perchlorate through water or food can negatively affect thyroid hormone synthesis, which is crucial for metabolism and neural development. Current remediation methods involve physical-chemical techniques, but alternative treatments are needed due to waste generation. This review discusses hybrid technologies that are being researched for the treatment of perchlorate and other emerging contaminants.

Summary: This study investigated the effects of environmental characteristics on the degradation of chlorpyrifos by Hortaea sp. B15, as well as the enzyme activity and metabolic pathway. The results showed that the highest bacterial growth was achieved after 20 hours of incubation in a culture with 100 mg/L chlorpyrifos. The optimal pH for chlorpyrifos degradation was pH 9, and the presence of non-ionic surfactant Tween 80 enhanced the degradation and bacterial growth. Metabolites such as 3,5,6-trichloropyridin-2-ol and 2-pyridinol were identified in the degradation process.

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.
