Due to their substantial biomass and rapid growth, emergent plants found in wetlands are viewed as excellent sources for biochar production, which has been demonstrated serve an effective substitute absorbite the effluent treatment. This article systematically contrasted physicochemical properties of derived from each section Iris sibirica L. (designated BCR, BCS, BCL) under identical pyrolysis conditions, order assess effectiveness removing cadmium (Cd) effluent. Experimental results indicated that removal efficiencies Cd among various biochars followed BCS (19.92 mg/g) > BCL (19.89 BCR (13.22 mg/g). The Cd2+ by is primarily governed chemisorption, described Langmuir Freundlich models. Moreover, different adsorption kinetic models, e.g., first-order kinetics, second-order intra-particle diffusion, Elovich model, were performed elucidate process. Compared proportions ion exchange precipitation more superior reaching 54% 31%, respectively, could adsorbent metal ions, achieving maximum capacity. In addition, (46%) was predominant during process through BCR. Therefore, suitable acidic wastewater study provided in-depth understanding behavior obtained part (roots, stems, leaves) wetland introduced a new option efficient utilization waste biomass.
