abstract = {Sargassum algae has become a major environmental issue due to its abundance in the
Pacific Ocean with hundreds of tons reaching the beaches of the Mexican Caribbean every year. This
generates large quantities of decomposing organic matter that have a negative impact on the region’s
economy and ecosystems. Sargassum valorization has turned out to be a fundamental aspect to
mitigate its environmental impact. This study proposes the use and application of untreated Sargassum
biomass for the decontamination of waters polluted with lead (Pb) and cadmium (Cd) through single
and binary adsorption tests. Physicochemical and textural properties examined by SEM, XRD, and
FT-IR elucidated that Sargassum biomass is viable to be used as a potential environmental benign
adsorbent, exhibiting Cd(II) and Pb(II) adsorption capacities as high as 240 mg g-1 and 350 mg g-1,
respectively, outperforming conventionally used adsorbents. This is attributed to its morphology,
favorable surface charge distribution, and the presence of -OH and -COH groups. A strong affinity
between the biomass and metal pollutants was evidenced by a thermodynamics study, showing
a spontaneous and endothermic process. This work sets a practical route for the utilization of the
Sargassum biomass, demonstrating its applicability as a potential material for heavy-metal-polluted
water remediation, making a substantial contribution to a circular economy system.},
