Starch-assisted facile gel formation method for the synthesis of Fe-Mn binary oxide for the simultaneous removal of As(iii) and As(v).

ABSTRACT: Researchers have significantly focused on eco-friendly methods for nanomaterial synthesis to reduce the reliance on hazardous chemicals. In light of this, this study presents an eco-friendly, straightforward, alkali-free method for synthesizing iron-manganese (Fe-Mn) binary oxide (FMBO) and their single oxides by adopting a direct gel formation approach using starch. The synthesized materials were characterized through FTIR, FESEM, EDX, and XRD. Based on the characteristics of the synthesized materials, the probable formation mechanism of nanomaterials within the starch matrix via gel formation was comprehensively investigated. The presence of MnO₄ ^- resulted in faster gelation than Fe³⁺ owing to its stronger oxidizing properties, leading to a more r
