Valorization of Pretreated Salvinia molesta Biomass for Ciprofloxacin Biosorption: Kinetic Performance, pH-Dependent Mechanisms, and Circular Economy Implications. [PDF]

Water Environ Res
Powdered Salvinia molesta biomass efficiently removed ciprofloxacin under environmentally relevant conditions, with optimal sorption at a near‐neutral pH. This study highlights invasive plant biomass valorization as a low‐cost circular solution for decentralized water treatment.
