The modification of widespread plant and their use as low-cost and efficient biosorbents is a prospective way for dissolving environmental problems. In this research, the adsorption capacity of biosorbent based on the Ambrosia arthemisiifolia was improved by modification with magnetite. The adsorption capacity of the modified magnetic biosorbent was determined with the help of cationic dye Malachite Green (MG). The maximum of MG adsorption capacity, after 20 min, was 7.65 mg/g, with removal efficiency of 100%. The adsorption kinetic of the MG was described by the pseudo-second order model. FTIR analyses also confirmed biosorption of MG on magnetic biosorbent. The present study verified that magnetic biosorbent can be used as an economic and effective adsorbent for removal of MG from aqueous solutions.
