A high surface area lentil processing waste-based activated carbon was synthesized by microwave-assisted K2CO3 chemical activation and then successfully converted into a ferrospinel composite. The ferrospinel composite was characterized with BET, FTIR, XRD, XPS, FE-SEM, EDX mapping, Raman and VSM techniques and the detailed characterization analysis confirmed the successful formation of the ferrospinel composite. It was also applied as an effective adsorbent material in the treatment of 2,4-dichlorphenoxyacetic acid herbicide bearing wastewater. The pseudo-second order model better defined the kinetic pathway of the adsorption while the isothermal data indicated the best suitability to Langmuir model. The maximum adsorption capacity of the ferrospinel composite towards 2,4-dichlorophenoxyacetic acid was 400 mg/g at 45 degrees C. Thermodynamic studies showed the favorability and spontaneity of the adsorption process.eninfo:eu-repo/semantics/closedAccessLentil Processing WasteMagnetic CompositeMicrowave EnergyFerrospinel NanoparticlesHerbicide AdsorptionArticle18WOS:0006024301000072-s2.0-8509260617110.1016/j.scp.2020.100338Q1Q2
