Abstract

In this study, microwave-assisted activated carbon was produced from lentil processing waste K2CO3 chemical activation at optimum production conditions. The synthesized optimal activated carbon with a high surface area (1875 m2/g) was used as a matrix for ferrospinel composite. CuFe2O4 nanoparticles were embedded to the synthesized optimal activated carbon and a novel magnetic composite material was fabricated. A detailed structural and textural analysis of as-prepared ferrospinel composite material was made by using various characterization techniques including Fourier transform infrared spectroscopy, Brunauer-Emmett-Teller analysis, X-ray photoelectron spectroscopy, and Vibrating sample magnetometer analyses.
