Solid-Phase Activation During the Degradation of Tetracycline by Modified Activated Carbon–Persulfate Composite

Catalysts, Год журнала: 2025, Номер 15(2), С. 169 - 169

Опубликована: Фев. 12, 2025

In this study, the novel composite materials of activated carbon (AC) and persulfate (PS) doped by nitrogen (N) sulfur (S) were successfully synthesized through one-step mechanical ball milling. Different from previous liquid-phase activation process PS, direct in situ solid-phase PS was achieved newly generated chemical bonds between AC PS. The increased crystal surface exposure highly electronegative atoms provided more reactive sites for modified composites, enabling them to extract electrons pollutant. Compared S doping, N-doped exhibited a higher oxidative degradation ability, with removal rate 93.6% tetracycline (TC, 40 mg/L) within min. interactions that occur interior avoid limitations mass transfer solid–liquid interface, thus expanding pH application range catalytic reaction minimizing interference other components solution. synergistic effect active oxygen species electron is main mechanism promoting pollutant degradation. This research puts forward new insight into approach proposes feasible method advanced treatment TC wastewater.

Challenges and advances in nanocellulose-based adsorbents for dye removal: mechanisms and future directions

Deleted Journal, Год журнала: 2024, Номер 7(1)

Опубликована: Дек. 18, 2024

Abstract The rapid growth of the textile industry has led to a sharp increase in dye-filled wastewater, posing significant environmental concern. Adsorption is promising method for dye removal, but traditional adsorbents often fall short due limited capacity, lack sustainability, and low selectivity. Nanocellulose-based materials have shown great potential, with some achieving high adsorption capacities, such as 3429.23 mg/g Congo Red on cellulose-based aerogel 2282.3 malachite green magnetic nanocellulose-based adsorbents. These follow various models, including Langmuir Freundlich isotherms, kinetic models pseudo-second-order model indicating strong interactions target dyes. This review thoroughly examines adsorbents, exploring their types, properties, preparation methods. analyses interactions, factors influencing adsorption, provides an in-depth look at kinetics, thermodynamics. Also, this aims clarify true potential summarizing recent advancements while identifying research gaps future directions support further development field.
