Abstract In order to effectively treat harmful algal blooms and avoid secondary pollution by chemical substances, maglev beads VMB@Fe₃O₄@CS were synthesized through a novel method combined with magnetic flocculation and float flotation which use vitrified microbeads, Fe₃O₄ and chitosan as raw materials, to remove Anabaena flos-aquae and Microcystis aeruginosa. The results showed that the optimal removal efficiencies of the two species of algae were 99.01% (0.12g/L) and 98.6% (0.21g/L), respectively. VMB@Fe₃O₄@CS achieved a high removal rate (> 60%) in a wide pH range (4~10) and water temperature range (5~35°C), and the increase of ionic strength had a negative effect on the removal of microalgae. Through morphological observation, surface hydrophobicity and Zeta potential analysis, it was determined that electrostatic attraction and adsorption bridging were the main flocculation mechanisms of maglev beads on algal cells. The experimental results show that the prepared VMB@Fe₃O₄@CS has a great potential to control harmful algal blooms.
