Summary: This study investigated the adsorption of tetracycline onto different clays and analyzed the adsorption mechanisms and influencing factors. Bentonite showed the highest adsorption capacity due to its swelling characteristic, interlayer cations, and tetracycline molecular size. Adsorption occurred on the external surface and in the interlayer space of bentonite, with both physical and chemical mechanisms involved. The adsorption process was partially reversible and endothermic.

Summary: Chitosan/bentonite beads (CsB) composites were prepared for the removal of reactive orange 16 (RO16) and methylene blue (MB). The adsorption results showed that Cs20B80 was the best adsorbent for MB and RO16 dyes. The characteristics of Cs, B, and Cs20B80 were investigated using various techniques. The adsorption process was affected by contact time, initial concentration, temperature, adsorbent quantity, ion strength, and solution pH.

Summary: The combination of adsorption process and electrocoagulation is an effective technique for dye removal. In this study, calcinized and non-calcinized composites based on bentonite and sodium zeolite were prepared and tested for the adsorptive removal of different dyes. Factors such as contact time, initial dye concentration, and temperature were investigated. The results showed that the calcinized nano-composite material had better adsorption capacity and could be used as a low-cost alternative for dye removal.

Summary: The expansion of red-bed weathered expansive soil when exposed to water is driven by hydration forces and repulsive forces in the electric double layer. Grain orientation of the soil plays a significant role in influencing the microscopic model. Experiments indicated that the unloading expansion rate decreased with higher cation concentration and lower pH value, but increased with a larger hydration cation radius, providing a theoretical basis for landslide prevention and control.

Summary: A novel magnetic separator was designed to capture chromium ions in tanning wastewater using magnetic nanoparticles. The efficiency of the separator was investigated by studying the effects of Fe3O4 magnetic particle concentrations, magnetic bar spacing, and liquid flow velocities in a simulated system. The results showed that under certain conditions, the capture efficiency of the Fe3O4 magnetic nanoparticles could exceed 99.4%, making it suitable for large-scale heavy metal wastewater treatment.

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.
