The effective immobilization of zerovalent copper and cobalt nanoparticles onto a glycine-coated magnetite core was corroborated through analytical techniques such as FTIR, XRD, EDS, and XPS.

Characterization results revealed that, under optimal conditions, specifically a biomass-to-activator mass ratio of 1:2 and a carbonization temperature of 600 °C, the MgBC possessed a specific surface area of 267.18 m² g⁻¹, a nitrogen content of 3.65 at%, and an oxygen content of 8.72 at%.

The optimal MgBC demonstrated rapid kinetics and substantial adsorption capacity, achieving a Langmuir maximum capacity of 27.77 mg g⁻¹ at a solution pH of 7. The superior performance of MgBC can be ascribed to its augmented specific surface area, optimized porosity, and heightened N, O content. The adsorption data adhered well to the pseudo-second-order model and Langmuir model suggested that physical adsorption with monolayer coverage predominated, albeit with some involvement of chemical processes. Additional mechanistic analysis confirmed that the attachment of Cr(VI) to MgBC primarily resulted from a synergistic interaction of electrostatic attraction, surface complexation and reduction.
