Summary: Shrimp shells-derived chitosan was utilized as an effective adsorbent for the removal of reactive red 198 dye, with adsorption affected by parameters like pH, concentration, and temperature. The study concluded that Langmuir isotherm model and pseudo-second-order equation were optimal for describing the adsorption process. Further optimization using central composite design matrix and response surface methodology revealed the potential for broader applications of this material in wastewater treatment.

Summary: This study investigated the impact of parameters such as solution pH, temperature, contact time, and the presence of phosphate and nitrate ions on the adsorption of Reactive Red 120 dye by Polyamide Nylon 6 microplastics. The highest uptake was observed at pH 2.0, while increasing temperature led to decreased sorption. Equilibrium was reached after 7 hours, and the adsorption followed a pseudo-second-order kinetic model. The Langmuir isotherm model provided the best fit for the experimental data, with a maximum adsorption capacity of 3.96 mg/g at pH 2.0 and 295 K. Thermodynamic analysis indicated that the adsorption process was spontaneous, exothermic, and associated with a decrease in entropy at the solution/solid interface. Future studies will explore the impact of aging on the adsorptive properties of Polyamide Nylon 6 towards Reactive Red 120 dye.

Summary: In this study, a novel composite material nZVI/Alk-Ti3C2Tx was developed for the simultaneous adsorption and reduction of U(VI) in anoxic conditions, showing efficient removal efficiency and high uptake capacity. The composites exhibited high U(VI) removal rates in different environmental media. The study also clarified the different pathways for U(VI) elimination based on the reaction mechanisms between U(VI) and nZVI/Alk-Ti3C2Tx.

Summary: This study investigated the removal of Reactive Red 198 (RR198) dye from water using Boehmite/Fe3O4/Graphene Oxide (GO) magnetic nano-adsorbent. The synthesized materials were characterized using SEM, FTIR, BET, XRD, and TGA. The effects of various variables on the removal of RR198 were studied, and the highest removal efficiency was achieved under specific conditions. The adsorption process followed the Langmuir adsorption isotherm and the PSO kinetic model.

Summary: Phosphorylated chitosan (P-CS) was successfully synthesized and shown to have good adsorption properties towards anionic dye Acid Red 88, making it a promising adsorbent for water treatment applications. The adsorption mechanism of P-CS/AR 88 system is mainly driven by electrostatic attractions, H-bonding, and n-pi interactions, as revealed by FTIR spectroscopy and DFT calculations.

Summary: In this study, chemically modified lychee peels were used as an adsorbent to remove Reactive Red 195 dye from water. The results showed that the solution pH had a significant effect on the removal efficiency, with the highest removal efficiency of 94.5% achieved at pH 4.0. The adsorption process followed the Langmuir model and pseudo-first-order kinetic model, indicating favorable adsorption at low temperatures. The desorption efficiency was also evaluated, and the regenerated adsorbent showed a retention of over 77.3% efficiency after five cycles.

Summary: A novel magnetic anion exchange microbead (NAEM) with excellent reuse and anti-fouling performance was developed for the removal of reactive dye sunset yellow (FCF). NAEM exhibited a significantly higher initial adsorption rate and equilibrium adsorption capacity for FCF compared to commercial anion-exchange resins. The multilayered adsorption of FCF on different resins suggests the contribution of physical adsorption. NAEM also demonstrated enhanced anti-interference capacity and prolonged reusability compared to other resins.

Summary: Hybrid adsorbents made from banana peels potassium-barium (BK-Ba), orange peels bismuth-cobalt (ORBi-Co), potato peels sodium-strontium (PPNa-Sr), and a mixture of potato, orange, and banana peels (MBi-Fe) were prepared and tested for the removal of reactive red methyl 4 BL dye. The optimal pH for each adsorbent was determined to be 2 (27 mg/g) for BK-Ba, 2 (40 mg/g) for ORBi-Co, 7 (35 mg/g) for MBi-Fe, and 12 (45 mg/g) for PPNa-Sr. The maximum adsorption capacities were achieved at a dose of 0.05 g/50 mL and an initial dye concentration of 50 ppm for BK-Ba, ORBi-Co, and PPNa-Sr adsorbents (35, 36, 48 mg/g), and 75 ppm for MBi-Fe adsorbent (42 mg/g). The optimal reaction time was found to be between 45 and 60 minutes with a temperature of 35 degrees C. The adsorption processes followed the pseudo-first-order kinetic model and the adsorption isotherms exhibited Langmuir behavior. The study also showed that the adsorption was exothermic. Overall, the hybrid adsorbents showed effective removal of the dye.

Summary: In this study, nitrogen-doped zero-valent iron/biochar (ZVI/BC-N) with a larger specific surface area and porous structure was successfully prepared by oxidizing waste corn cobs and grafting them with diethylenetriamine (DETA). ZVI/BC-N exhibited stronger adsorption performance in phosphorus removal, with a multimolecular layer chemisorption mechanism. This study provides a simple method for preparing biochar composites with a high ZVI content and presents a new approach for efficient removal of phosphorus from water.
