Abstract Extracellular polymers (EPS) produced by microalgae are considered an important factor in the process of biosorption environmental contaminants. The study investigated impact mixotrophic cultivation unicellular algae Chlorella vulgaris , Parachlorella kessleri and Vischeria magna on specific productivity yield total soluble EPS as well biochemical composition sorption properties extracellular order to explore their potential be used for biosorption. results showed that conditions enhanced contributed changes monomer EPS. Higher levels sugars, reducing protein, phenolic compounds reduced content uronic acids were observed isolated conditions. Rhamnose, xylose, mannose, glucose, galactose detected samples. FTIR ICP-OES applied characterise structure role Pb(II) removal. carboxyl groups hydroxyl played process. from C. cultures highest removal capacity.

Heavy metal wastewater often contains multiple ions, and competition among them reduces the adsorption efficiency of microalgae. Enhancing this is crucial for improving heavy removal. This study optimized lysine addition to facilitating formation a ternary complex between microalgae, lysine, metals, thereby enhancing in both single- mixed-metal systems. In single-metal system at 64 mg/L, improved removal rates copper, zinc, cadmium by 13.96%, 41.21%, 33.26%, respectively. binary systems (Cu-Zn, Cu-Cd, Cu-Pb) 32 increased copper 11.81%, 15.71%, 25.25%, while cadmium, lead 15.41%, 12.51%, 3.93%, Competitive analysis revealed that most strongly inhibited adsorption, significantly suppressed zinc adsorption. Mechanistic investigations using 3D-EEM, FTIR, XPS demonstrated humic substances extracellular polymeric (EPSs) microalgae play key role binding. interaction increases number carboxyl functional groups on cell surface, microalgae’s capacity adsorb metals.
