Published: Jan. 1, 2025

Abstract The present investigation deals with feasibility to use available biomass waste, Terminalia arjuna seed as cost‐effective sorbent for reactive orange 16 (RO16) dye elimination from wastewater. study centers around the modification of biochar (TASB) by applying one‐step synthesis procedure, using melamine a nitrogen doping agent and phosphoric acid (H 3 PO 4 ) chemical activator. effectiveness modified nitrogen‐doped (ND‐TASB) was assessed on RO16 removal aqueous medium. Surface morphology synthesized identified Fourier transform infrared spectroscopy (FTIR) scanning electron microscopy (SEM). Modified ND‐TASB reflected enhancement in adsorption efficacy, at pH 4, maximum 95% observed. By utilizing TASB an adsorbent, medium examined under varying experimental conditions like pH, adsorbent amount, exposure period were reported 1.5 1 g 40, 60 min respectively RO (200 mg/L concentration). Isotherm kinetic results appropriate Langmuir isotherm pseudo second‐order models. Maximum sorption efficiency 2.51 mg −1 , whereas NB‐TASB exhibited 4.84 that is, 93% enhancement. Alterations free energy (Δ G °), enthalpy H entropy S °) process analyzed assess nature phenomenon. negative values Δ ° confirms phenomenon spontaneous feasible. Enthalpy value −60.39 kJ mol had 182.72 J K ND‐PKSB. Phytotoxicity revealed or treated solution enhanced pearl millet seedlings growth biochemical variables better ND‐PKSB solution. Moreover, regenerated adsorbents high up five consecutive cycles. These findings establish acts durable, multifaceted, recyclable environmentally benign superior properties its application industrial scale.

Recent Advances on Porous Biochar: From Production to Remediation of Organic Pollutants from Water and Future Perspectives

ChemistrySelect, Journal Year: 2025, Volume and Issue: 10(8)

Published: Feb. 1, 2025

Abstract Organic pollutants in aqueous pose a serious threat toward ecosystems and human health, marking them as pressing global environmental issue. In response to this urgent challenge, scientists have been pursuing efficient methods minimize their presence, biochar has regarded promising material. Although some studies reported by using address specific pollutant, they still lack systematic analysis for synthesis removal mechanisms broad spectrum of pollutants. This paper aims present review on recent advances dyes, antibiotics, pesticides via adsorption oxidative degradation. The focus is rationalize factors that control pore size, functional groups, ability function feedstocks synthetic conditions, temperature identified the most critical factor. Modifications, such doping heteroatoms metals, are important enhance biochar. challenges opportunities future exploration discussed, hoping inspire more researchers participate fascinating area.
