Summary: The presence of polycyclic aromatic hydrocarbons (PAHs) in wastewater, especially acenaphthene (ACN), has become a major concern due to their potential negative health effects. This study used activated carbon from oil palm leaves to remove ACN from wastewater through adsorption. The optimization of pH, activated carbon dosage, and contact time was conducted using response surface methodology (RSM) combined with central composite design (CCD). The results showed that pH 7, an activated carbon dosage of 2.62 g/L, and a contact time of 71.67 min were the optimal conditions for achieving a removal efficiency of 98.88%. The RSM model was found to be significant, allowing for the prediction and verification of the adsorption results.

Summary: In this study, the response-surface methodology (RSM) was used to optimize the synthesis of a Mg-doped UiO-66-NH2 nanocomposite for enhanced phosphate removal. The optimized parameters for the nanocomposite fabrication were determined to be a magnesium concentration of 1.18 mM, solvothermal temperature of 120 degrees C, and solvothermal time of 12.69 h. The optimal sample showed a P removal efficiency 1.75 times higher than that of pristine UiO-66-NH2. Analysis of the adsorbent revealed that the P removal process was primarily based on chemical interactions. Furthermore, the adsorbed P could be effectively recovered using different concentrations of sodium hydroxide.

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.
