“…Likewise, the absence of hysteresis loops in the magnetization curve implies that the adsorbent has superparamagnetic nature (Hu et al 2023 ; Xiong et al 2023 ). This value is much greater than the previously reported magnetic adsorbents for 2, 4-D remediation; 11 emu/g (Demiti et al 2022 ), 3.98 emu/g (Sayğılı and Sayğılı 2022 ), 2.57 emu/g (Vinayagam et al 2022 ), 6 emu/g (Herrera-García et al 2019 ), and 37.28 emu/g (Nethaji and Sivasamy 2017 ). This could be a consequence of the small size of the synthesized Fe 3 O 4 @NiS NPs-AC, as highlighted in the XRD analysis.…”

“…The adsorbent’s recovery is assisted by its magnetic properties due to the rapid separation induced by an external magnetic field (Demiti et al 2022 ). The magnetic characteristics of the synthesized Fe 3 O 4 @NiS NPs-AC were determined using the VSM method by measuring its magnetization behavior as a function of the applied magnetic field between ± 20 kOe at ambient temperature.…”

“…Pesticides are usually utilized extensively for agricultural use for several goals, including inhibition of growth weeds, control of pests, plant development control, and expansion of animal and plant biomass production. To avoid their contaminating soil and water after use, they must be eliminated (Demiti et al 2022 ). The low cost and high selectivity of 2,4-dichlorophenoxyacetic acid (2,4-D) make it an ideal herbicide for controlling broadleaf weeds (Georgin et al 2021a ).…”

“…This means that it has the potential to contaminate water sources and seriously harm aquatic ecosystems. Due to 2,4-D’s economic viability and widespread consumption, there is a significant priority regarding the harm to human health brought on by exposure through inhalation, swallowing, and skin intake (Demiti et al 2022 ). 2,4-D belongs to endocrine-disrupting chemicals.…”

“…Activated carbon (AC) represents the most widely used carbonaceous materials as adsorbents since it has high surface area, well-defined porous structure, and good adsorption capacity, as well as its low cost and ease of recovery. Thus, it can be utilized for eliminating organic contaminants from water (Demiti et al 2022 ).…”

The upgrade of sustainable resource waste into a valuable and beneficial material is an urgent task. The current paper outlines the development of an economical, sustainable, and prolonged adsorbent derived from Sargassum siliquastrum biomass and its use for potent 2,4-dichlorophenoxyacetic acid (2,4-D) removal. A simple carbonization approach was applied to obtain the highly functionalized carbon structure, which was subsequently transformed into a novel magnetic nanoadsorbent. The magnetic nanoadsorbent was characterized using Fourier transform infrared spectrometer (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), Brunauer Emmett Teller (BET)-specific surface area, and vibrating sample magnetometer (VSM). The characterization results confirm the successful formation of a high specific surface area and a uniform distribution of Fe3O4/NiS NPs grafted activated carbon. The adsorption kinetics was more accurately described via the pseudo-second order model; nevertheless, the isothermal data showed that the Langmuir model was most suitable. The monolayer adsorption capacity for 2,4-D was 208.26 ± 15.75 mg/g at 328 K. The favourability and spontaneity of the adsorption process were demonstrated by thermodynamic studies. The adsorbent displayed exceptional selectivity for 2,4-D and high stability in multi-cycle use. Electrostatic attraction, π-π stacking, and hydrogen bonding were all believed to have an impact on the sorbent’s robust 2,4-D adsorption. Analyses of real tap and Nile River water samples showed little effect of the sample matrix on 2,4-D adsorption. This study presents an innovative approach for developing highly efficient adsorbent from natural biomass and offers an affordable way to recycle algal waste into beneficial materials.

Per uorinated compounds (PFCs) cause environmental pollution and serious health issues. Therefore, magnetic uorinated porous carbons (M-FPCs) derived from the carbonization and further uorination of Fe-Zr MOFs were used as novel adsorbents to investigate the possibility of PFC removal from wastewater. Investigation of the adsorption behavior of PFCs on M-FPCs revealed that the isotherms conformed to the Langmuir model and kinetics t the pseudo-second-order model. Simulations using the Weber-Morris and Boyd diffusion models indicated that the adsorption of PFCs on M-FPCs involved external mass transfer rst, followed by intraparticle diffusion, where lm diffusion was the primary controlling process. M-FPCs with maximum adsorption ranging from 518.1-919.3 mg g − 1 for studied PFCs were adopted to remove PFCs from simulated wastewaters of textile mill and leather factory. Up to 98.1-100.0% of PFCs were removed within 15 min, and the residual levels of PFCs reached drinking water standards after treatment, which suggests the promising application of M-FPCs in the removal of PFCs from wastewater.
