AimCan protein waste from the leather industry be converted into a magnetic nanocomposite for effective oil removal and subsequent material recovery?
MethodMaterials synthesis and characterization, adsorption studies, magnetic separation, thermal conversion.
ProcedureA magnetic nanocomposite was synthesized by combining collagen from leather industry waste with superparamagnetic iron oxide nanoparticles (SPIONs). The interaction between collagen and SPIONs was confirmed using calorimetric, microscopic, and spectroscopic techniques. The nanocomposite's oil absorption capacity and magnetic recovery were tested. Finally, the oil-adsorbed nanocomposite was heat-treated to convert it into a graphitic nanocarbon material.
