Article highlights Crawfish-shell biochar (CSB) pyrolyzed at 350°C showed the highest Sb(III) adsorption and oxidation. DFT calculations highlighted complexation, H-bonding and π–π interactions as key removal mechanisms. Sb(III) oxidation was mainly governed by persistent free radicals and electron transfer capacity of biochar.
