Pharmaceutical analysis by a novel spinel ferrite nanocomposite derived from a biomaterial-based activated carbon.

Microwave-assisted activated carbon was fabricated from lentil waste (LW) by KCO chemical activation at optimum production conditions and the synthesized optimal activated carbon (LWAC) with a high surface area (1875 m/g) was used as a matrix for spinel ferrite composite production. CuFeO nanoparticles were embedded to LWAC and a novel magnetic composite material (M-LWAC) was synthesized. A detailed structural and textural analysis of M-LWAC was made by using various characterization techniques. M-LWAC was also used as an effectual remover for tetracycline (TC) bearing wastewater with 384.62 mg/g of adsorption capacity. Kinetic, isotherm and thermodynamic analyses indicated the fast, effective and spontaneous adsorption of TC by M-LWAC.
