Coagulation-assisted removal of polystyrene microplastics from aqueous solution using amine-functionalized multi-walled carbon nanotubes with okra extract

Coagulation-assisted removal of polystyrene microplastics from aqueous solution using amine-functionalized multi-walled carbon nanotubes with okra extract

Polystyrene microplastics (PS MPs) are widely distributed in aquatic environments and pose ecological and potential human-health risks. This study investigated the coagulation-assisted removal of PS MPs using MWCNTs@NH2 in combination with okra extract as a natural coagulant aid. A Box–Behnken design was used to evaluate the effects of MWCNTs@NH2 dose (0.2–1 g/L), initial PS concentration (50–400 mg/L),…
