Uptake of BF Dye from the Aqueous Phase by CaO-g-C3N4 Nanosorbent: Construction, Descriptions, and Recyclability

Removing organic dyes from contaminated wastewater resulting industrial effluents with a cost-effective approach addresses major global challenge. The adsorption technique onto carbon-based materials and metal oxide is one of the most effective dye removal procedures. current work aimed to evaluate application calcium oxide-doped carbon nitride nanostructures (CaO-g-C3N4) eliminate basic fuchsine (BF) wastewater. CaO-g-C3N4 nanosorbent were obtained via ultrasonication characterized by scanning electron microscopy, X-ray diffraction, TEM, BET. TEM analysis reveals 2D nanosheet-like nanoparticle architectures high specific surface area (37.31 m2/g) for as-fabricated nanosorbent. results demonstrated that variation concentration impacted elimination BF CaO-C3N4 while no effect pH on was observed. Freundlich isotherm Pseudo-First-order kinetics models best fitted CaO-g-C3N4. highest capacity determined be 813 mg. g−1. mechanism related π-π stacking bridging hydrogen bond, as FTIR study. may easily recovered solution effectively employed in at least four continuous cycles. fabricated adsorbent display excellent can used potential sorbent purification.
