摘要	Harmful algal blooms (HABs) are growing threats that cause tens of billion dollars economic loss annually. Aiming at efficient disposal of HABs, a cheap and eco-friendly cationic straw was developed by etherification of wheat straw, which replaced hydroxyl groups on cellulose by quaternary ammonium groups. It endowed the cationic straw with high positive charge and achieved 93.92% of harvesting efficiency by enhancing HABs cells aggregation via charge neutralization. Different from inorganic salts-based flocculants, HABs harvesting by the cationic straw is a spontaneous and exothermic process with negative & UDelta;G and & UDelta;H under all adsorption con-ditions. Thermodynamics and kinetics analysis elucidated that HABs adsorption process by cationic straw were mainly driven by physical forces. Together, cationic straw preparation and HABs harvesting processes were comprehensively optimized with orthogonal experiments. The work may inspire cost-effective HABs disposal and fill knowledge gaps of process nature for HABs harvesting.
