In recent decades, the tetracycline (TC) concentration in aquatic ecosystems has gradually increased, leading to water pollution problems. Various mineral adsorbents for the removal of tetracyclines have garnered considerable attention. However, efficient adsorbents suitable for use in a wide pH range environment have rarely been reported. Herein, a phytolith-rich adsorbent (PRADS) was prepared by a simple one-step alkali-activated pyrolysis treatment using phytolith as a raw material for effectively removing TC. PRADS, benefiting from its porous structure, which consists of acid-and alkali-resistant, fast-adsorbing macroporous silica and mesoporous carbon, is highly desirable for efficient TC removal from wastewater. The results indicate that PRADS exhibited excellent adsorption performance and stability for TC over a wide pH range of 2.0− 12.0 under the coexistence of competing ions, which could be attributed to the fact that PRADS has a porous structure and contains abundant oxygen-containing functional groups and a large number of bonding sites. The adsorption mechanisms of PRADS for TC were mainly attributed to pore filling, hydrogen bonding, π−π electron-donor−acceptor, and electrostatic interactions. This work could offer a novel preparation strategy for the effective adsorption of pollutants by new functionalized phytolith adsorbents.

The removal of antibiotic residues from environmental media is a significant challenge in the field of chemistry. In this work, we presented a simple and efficient method for eliminating tetracycline hydrochloride (TC) and chloramphenicol (CAP) from water. Initially, 1,4‐dichlorobenzene and ferrocene were employed as starting materials for the synthesis of hypercrosslinked polymers (HFDs) via Friedel–Crafts alkylation facilitated by a cross‐linking agent. Subsequent to this, an efficient magnetic adsorbent material (MHFD) was developed by the in situ oxidation of the iron source incorporated within the polymer matrix of HFDs. The resulting MHFDs demonstrated an impressive maximum Brunauer–Emmett–Teller (BET)–specific surface area of 1190 m2/g and exhibited a peak saturation magnetization of 11.8 emu/g. This work investigated the effects of four factors on the adsorption performance of MHFD‐10, including contact time, solution pH, dosage of MHFD‐10, and initial antibiotic concentration. The results revealed a remarkable conformity of the adsorption kinetics with the pseudo‐second‐order model and the adsorption isotherms with the Langmuir model. Thermodynamic analysis revealed that the adsorption process is spontaneous and exothermic. Specifically, at a temperature of 20°C, MHFD‐10 achieved maximum adsorption capacities of 193.95 mg/g for CAP and 268.60 mg/g for TC. Furthermore, these materials exhibited exceptional reusability, maintaining high adsorption capacities even after undergoing five consecutive reuse cycles.

Photocatalysis is an efficient technology for the degradation of pollutants. However, there is still much room for improvement in its degradation efficiency. In this study, a pyrrolic N‐rich g‐C3N4 (PN‐g‐C3N4) framework was synthesized with transition metal M (M = Fe, Co, Ni, Cu, Cr, and Mn) atomic sites coordinated onto it. Then, a series of single atomic metals M anchored to PN‐g‐C3N4 (M/PN‐g‐C3N4) are constructed for peroxodisulfate activation. Their order of catalytic activity follows Fe>Cr>Ni>Cu≈Co>Mn, in particular the degradation rates of the TCH for Fe‐PN‐g‐C3N4 are 3.74 times higher than that of undoped PN‐g‐C3N4. These carefully regulated pyrrolic N‐rich Fe sites demonstrate outstanding performance in degrading organic pollutant. As an exemplary model, the Fe/PN‐g‐C3N4 catalyst efficiently drives the catalytic oxidation of TCH through Fenton‐like reaction under visible light, showcasing exceptional cycle stability and a broad effective pH range of 3.0 to 11.0. The synergy between photocatalysis and Fe doped catalysis results in increased generation and separation of charge carriers, along with the cyclic transformation of the Fe3+/Fe2+ couple. This combination significantly enhances the Fenton‐like performance, making it a highly effective process for pollutant degradation.
