Therefore,recycling and repurposing them for environmental purposes is garnering increasing attention.Hydrothermal carbonization (HTC) followed by phosphoric acid activation was used in this investigationto synthesize a novel activated hydrochar (AHPP) from pomegranate peels. X-Ray Diffraction,Fourier-transform infrared spectroscopy, Scanning electron microscopy with energy dispersiveX-ray spectroscopy, Brunauer, Emmett and Teller (BET) surface area analysis and Barrett-Joyner-Halenda (BJH) pore size distribution, and pH of zero charge were exploited to define thecharacteristics of AHPP, which was then used to assess the uptake of Basic Red 46 (BR46) dye inthe batch mode. Isothermal and kinetic investigations were accomplished with pH = 6, 0.5 g.L−1of adsorbent, 400 rpm at 298 K upon 60 min. The Freundlich model accurately presented theequilibrium curves with an adsorption capacity of 998.95 mg g−1, while the PSO kinetic modeladequately corresponded to the experimental data. Furthermore, thermodynamic data disclosedthat the process was spontaneous, endothermic, and linked to a growing disorder at the adsorbent-adsorbate interface. Lastly, the reuse investigation using HCl ascertained that AHPP mightbe recycled ten times, whereas a probable adsorption mechanism was proffered. Overall, it is possibleto conclude that activated hydrochar generated from pomegranate peels as cost-effectivewaste could be employed as an alternative sorbent in dining substantial effluents retaining BR46 PB Biocatalysis and Agricultural Biotechnology SN 18788181 YR 2023 FD 2023-07 LK http://hdl.handle.net/11093/4806 UL http://hdl.handle.net/11093/4806 LA eng NO Biocatalysis and Agricultural Biotechnology, 50, 102709 (2023) NO Financiado para publicación en acceso aberto: Universidade de Vigo/CISUG NO Ministerio de Ciencia e Innovación | Ref.
