Abstract
Nano ferrite bentonite clay composite (NFBC) is synthesized in this present work by using manganese (Mn) recovered from waste batteries, ferric nitrate and citric acid prepared by simple and cost-effective Indian sodium bentonite nanoclay (Na-IB) by sol-gel process and by using X-ray diffractrometer (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) Spectroscopy, Energy dispersive Spectroscope (EDS) characterized nanoparticles. The result shows that NFBC is sufficient for the excellent performance of AO dye photocatalytic degradation (98 %). Electrochemical study of prepared material with graphite electrode paste in 0.1 M KCl electrolyte showed excellent redox potential output as calculated by cyclic voltammetry and expanded its sensor activities to biochemical (Dextrose). We examined the efficacy of NFBC in the detection of Dextrose from an aqueous solution and compared the results with pristine MnFe2O4 NPs.
