Summary: This study focused on the removal of methylene blue from aqueous solution using Car-St-g-PVP as a cost-effective and biodegradable adsorbent. The experimental results showed that the adsorption process followed pseudo 2nd order kinetics and Langmuir's adsorption isotherms, indicating a chemisorption mechanism. Thermodynamic studies revealed a spontaneous nature of the adsorption process, with increasing randomness and endothermic nature as indicated by positive entropy and enthalpy values. The separation factor (RL) was less than one, confirming the feasibility of the adsorption process. Overall, Car-St-g-PVP demonstrated high efficiency in removing methylene blue and could be a promising option for wastewater treatment.

Summary: Novel starch phosphate grafted polyvinyl imidazole (StP-g-PIMDZs) was synthesized by attaching a phosphate group to starch polymer and grafting 1-vinyl imidazole onto the backbone of starch phosphate. The modified starches showed diminished crystallinity and increased thermal stability. They also exhibited high adsorption capacity for methylene blue dye, with StP-g-PIMDZ 3 achieving a maximum removal percentage of 95.4%. The adsorption process followed a pseudo second order kinetic model and Langmuir adsorption isotherm, and was thermodynamically feasible, spontaneous, endothermic, and favored chemi-sorption mechanism.

Summary: A novel magnetic asphalt-based activated carbon (MAAC) was prepared by a facile one-step method, and its adsorption performance for methylene blue (MB) was investigated. The MAAC showed a micro/mesoporous structure and had abundant oxygen functional groups on its surface, as well as uniformly dispersed zero-valent iron. Batch adsorption tests revealed that the MAAC had a maximum adsorption capacity of 710 mg/g for MB and exhibited good regeneration stability. These findings suggest that the MAAC could be a promising adsorbent for treating organic wastewater.

Summary: This study investigated the recovery of Gd3+ from real leachate of phosphogypsum using natural bentonite clay. The adsorption study revealed that the clay has typical bentonite characteristics and can effectively adsorb Gd3+. The kinetics and thermodynamics of the adsorption process were analyzed, and it was found that the Langmuir model and Avrami fractional order model were suitable for describing the adsorption isotherms and kinetic data, respectively. The study also showed that citric acid was an efficient desorbing agent for Gd3+ from the bentonite, and the clay could selectively recover Gd3+ from the real leachate of phosphogypsum.

Summary: Biosorption using a chitosan-pectinase blend (CPB) was studied for the removal of methylene blue (MB) dye from synthetic solutions. The blend showed a rough surface morphology and amorphous nature. Fourier-transform infrared (FTIR) analysis confirmed the successful blend formation. Maximum adsorption was achieved at pH 7.0, 30°C, 30 min contact time, and an adsorbent dosage of 2.5 g/L. The pseudo-second-order model provided the best fit, with the highest R2 value close to 1. The Temkin isotherm model showed the highest adsorption capacity at 16.81 mg/g. The blend demonstrated good desorption ability, allowing for reuse in dye removal.

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.
