Synthetic organic dyes, which are resistant to biodegradation, pose a notable health risk, potentially leading cancer and respiratory infections. Researchers have addressed this concern by exploring physicochemical methods remove dyes from wastewater. A particularly promising solution involves modified biochar adsorbents, demonstrate high efficiency in dye removal. Biochar, charcoal-like material derived biomass pyrolysis, offers advantages such as low cost, eco-friendliness, reusability. Beyond its role sustainable soil remediation, proves effective removing wastewater after undergoing physical or chemical modification. Acid–base activation metal–heteroatom impregnation enhances biochar's adsorption capacity. This comprehensive review examines the attributes of biochar, common for production modification, impacts raw materials, pyrolysis temperature, heating rate residence time. It further elucidates mechanism removal assessing factors influencing efficiency, including feedstock, pH, particle size, initial concentration, dosage reaction explores challenges, opportunities, reusability regeneration treating also discusses recent advances using adsorption-based biochar. The ultimately advocates enhancing performance through post-modification.

Superhydrophilic hyper-cross-linked polymers (HCPs) have become useful adsorbents for dye disposal due to their ultrahigh surface areas, permanent pores, and excellent water dispersion. Herein, a simple synthetic method has been proposed the construction of hydrophilic tetraphenylethylene (TPE)-based HCPs via molecular knitting subsequent one-step sulfonation, aiming significantly improve adsorption performance toward cationic dyes. Compared hydrophobic precursor with area up 1561 m2 g–1 (HCTPE), target sulfonated HCP named SHCTPE lower but improved hydrophilicity affinity (primarily electrostatic interaction) representative dyes including methylene blue (MB) rhodamine B (RhB), demonstrating impressive rates >99% removal efficiency (η) in only 5 s pseudo-second-order rate constants (k2) 58.7 83.4 g mg–1 min–1, respectively. The capacity also reached 1410 mg MB 1096 RhB, surpassing most HCP-based adsorbents. More importantly, exhibited stability after five cycles, its corresponding adsorption-treated solution showed considerable biocompatibility growth wheat seeds. Our strategy may provide an approach develop superhydrophilic efficient organic aqueous solutions.
