Summary: A series of lab-scale experiments were conducted to remediate Direct Blue 15 (DB15) dye using non-toxic halloysite nanotubes (HNT) for potential application in textile industrial effluent (TIE). The study found that the Brouers-Sotolongo adsorption isotherm model accurately predicted the adsorption behavior of HNT, and the pseudo-second-order reaction was identified as the predominant mechanism for the multi-step dye adsorption process. Additionally, the mass transfer during the process was diffusion-controlled, and thermodynamic assessments indicated that the process was physisorption.

Summary: The preparation of high performance, low cost and recyclable adsorbents is crucial for dealing with water pollution. Carbon foam (CF) is a promising adsorbent, but its uneven size distribution and lack of adsorption sites hinder its application. In this study, CF/CNTs/GO composites were successfully prepared, and the addition of CNTs and GO nanosheets significantly improved the adsorption performance. This work provides a low-cost fabrication technique for high-performance CF/CNTs/GO adsorbents and contributes to the treatment of contaminated water.

Summary: This study investigated the adsorption and recovery of cerium (Ce(III)), a rare earth element, from an aqueous solution using a sustainable hydrochar made from wood waste. The hydrochar contained various surface functional groups, which significantly influenced its adsorption capacity. The pH of the solution strongly affected the Ce(III) removal, with the highest removal efficiency achieved at pH 6.0. The hydrochar exhibited high efficiency in Ce(III) adsorption, with a maximum adsorption capacity of 327.9 mg g(-1) at 298 K. The adsorption kinetics followed the general order model, while the equilibrium process fit the Liu isotherm model. The Ce(III) adsorption mechanism on the hydrochar involved electrostatic interactions and chelation between surface functional groups and Ce(III). The hydrochar also demonstrated excellent regeneration capacity using sulfuric acid as an eluent. This research presents a sustainable approach for developing an efficient adsorbent for Ce(III) removal with excellent physicochemical properties.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
