A new and effective nanobiocomposite for sequestration of Cd(II) ions: Nanoscale zerovalent iron supported on sineguelas seed waste

- Immobilized nanoscale zerovalent iron on the sineguelas waste biomaterial was proposed.
- S-NaOH-NZVI was prepared with high chemical stability, offering a way to effectively use NZVI.
- Sineguela waste can prevent the aggregation of NZVI and provide opportunity for contaminants treatment.
- S-NaOH-NZVI was effective to remove Cd(II) ions from wastewater.
- XRD and EDX analysis indicated the presence of Cd(II) on the S-NaOH-NZVI surface.
