ABSTRACT The widespread use of PFAS in nonstick cookware, hydrophobic textiles, stain‐resistant fabrics, cosmetics, and floor coverings has led to their persistent presence wastewater streams, posing significant human health ecological risks. Exposure is linked adverse reproductive outcomes elevated blood pressure pregnant individuals, it negatively impacts aquatic ecosystems, particularly algal populations microbial communities. This evaluation focuses on biochar's efficacy cost‐efficiency removing from water, highlighting its potential as a sustainable remediation method. Biochar's high microporous volumes (0.1–1.0 cm³/g), aromaticity, surface oxygen‐containing functional groups make effective for adsorption. Various biochar production methods, such pyrolysis biomass waste, innovative modification techniques like acid treatment, ball milling, metal nanoparticle incorporation are explored enhance adsorption capacity. mechanisms, kinetics, thermodynamics onto examined, providing insights into molecular‐level interactions isotherms. Furthermore, machine learning models utilized understand the impact processing parameters removal efficiency. review also presents toxicological studies harmful effects exposure organisms humans, emphasizing urgent need strategies. Ultimately, biochar‐based approaches treating PFAS‐contaminated water underscored by optimizing physicochemical properties through along with predictive modeling behavior.
