Summary: Given the characteristics and risks of ammonia, the removal of ammonia is crucial for industrial production and environmental safety. This study modified viscose-based activated carbon fiber (ACF) with nitric acid impregnation to enhance its adsorption capacity for ammonia. The results showed that ACF-N-6 significantly increased the surface functional group content without destroying the physical structure of the activated carbon fibers. The highest adsorption capacity of ammonia by ACFs was 14.08 mmol/L at 293 K, which was a 165% increase compared to ACF-raw. The adsorption performance was strongly correlated with the carboxyl group content and relative humidity of the inlet gas. This research contributes to the development of efficient ammonia adsorption systems for industrial production and environmental safety.

Summary: This review explores the use of potassium hydroxide (KOH) in the production and modification of activated carbon. The activation process, carbonization, temperature, activation time, and KOH ratio are discussed, as well as their effects on surface area, surface morphology, and functional groups. The study finds that the pore structure, surface area, and pore size of activated carbon depend on the ratio of KOH, indicating that KOH influences the surface chemistry of the material. Additionally, the review calculates and evaluates the impact of various parameters on sorbent-sorbate interactions.

Summary: Modification of raw activated carbon using chemical solvents, such as triethylenetetramine, can enhance its adsorption performance. Liquid impregnation experiments were conducted to investigate the adsorption of triethylenetetramine on activated carbon for modification. The Langmuir isotherm model and pseudo-first-order kinetic model fitted well with the experimental data, with R2 values of 0.9883 and 0.9954, respectively. The adsorption process was found to be spontaneous, endothermic, and monolayer physical adsorption.

Summary: This article introduces a green method for producing activated carbon and combustible gas. The H2O and CO2 produced by pyrolysis of bamboo shoot shells are used as activators without the need for external reagents and gases. The prepared activated carbon has good adsorption properties for arsenic, with maximum adsorption capacities of 10.9 mg/g for As(III) and 16.0 mg/g for As(V). The main gaseous products are CO and H2, with a higher heating value of 11.7 MJ/Nm3. Thermogravimetric experiments were conducted to simulate the self-activation process and investigate the mechanism. This research will help improve the competitiveness of self-activation technology and reduce the production cost of activated carbon.

Summary: Zinc oxide-polypyrrole composites have shown the potential to effectively remove hazardous pollutants from water. The composite structure is different from zinc oxide, with a more acidic surface. The composite performs better under light, but its adsorption capacity decreases at neutral and slightly acidic pH due to electrostatic repulsion. However, at alkaline pH, the composite can still interact with the negatively charged Cr(VI) anions and demonstrate a higher adsorption capacity compared to zinc oxide.

Summary: This study examines the transformation of Chromium-Tanned Leather Shavings into carbon adsorbents for removing dyes from water. The results show that carbon materials with low chromium content and improved surface area can be obtained under high temperature and with the use of an activating agent. The surface charge of the adsorbents and the pore volume of the materials play a critical role in the adsorption process. This research demonstrates the possibility of using carbon materials derived from Chromium-Tanned Leather Shavings, which do not contain hazardous chromium particles, for efficient removal of polluting dyes from water.

Summary: In this study, a novel carbon aerogel (CAg) synthesized from sodium alginate (SA) was used as a precursor to create a double-B-site perovskite/carbon aerogel hybrid adsorbent ((Sr0.7Mn0.3Co0.5Fe0.5O3-delta)/CAg) (DB-perovskite/CAg hybrid). The adsorbent showed high removal efficiency for crystal violet (CV) and acid yellow 17 (AY17) in an aqueous system. The doping of Mn in the DB-perovskite/CAg hybrid led to improved adsorption through the introduction of abundant active sites and strengthening of metal-functional groups.

Summary: This study proposes a method using alkaline hydrolysis and an inorganic anion to separate chromium and protein to promote the hydrolysis of the Cr-O bond. De-chromed solids were used to synthesize carbon material for dye removal, while the chromium-rich solution was used as a re-tanning agent. The results show the potential for developing a chromium-protein separation method with minimal hydrolyzation, and the materials produced had good adsorption capacity for dyes and improved properties for re-tanned leather.

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.
