The coexistence of antibiotics and heavy metals in water environments always results greater toxicity compared to the single pollution. Consequently, development efficient economical technologies for removal is essential. This study prepared KOH-modified biomass (KCS) biochar (KCSB) coadsorption tetracycline (TC) Cu(II) an aqueous solution. performance mechanism TC are be explored through single-system binary-system studies, adsorption isotherms, kinetic models. indicate a synergistic effect between Cu(II); maximum capacity KCS 107.97 mg/g 58.44 mg/g, respectively. Meanwhile, KCSB exhibits 109.32 116.61 Cu(II). involved pore filling, hydrogen bonding, surface complexation, π–π interaction, ion exchange, precipitation. Among them, have stronger interactions with than exchange Cu(II), while has complexation KCS. provides more cost-effective adsorbent material simultaneous
