Nanoparticles have earned huge research interest due to their well known characteristics such as high specific surface, minimal environmental impact, ease in surface modification and low solubility in water. As a result, such materials have been used effectively to remove toxic metal ions from wastewater. Their adsorption potential has been further improved by modifying their surfaces by various means. In one such attempt, we have successfully synthesized magnetite and modified its surface by carbon while using glucose carbonization method. The as‐synthesized carbon coated magnetite (Mag@C) composite was characterized by Fourier transform infrared (FTIR) spectroscopy and the results were further supported by Energy dispersive X‐ray spectrometry (EDX), Scanning electron microscopy (SEM), Thermal gravimetric analysis (TGA), Zetastudies and X‐ray diffraction crystallography (XRD) like techniques. The Adsorption properties of Mag@C were explored for the removal of Cd 2+ and Pb 2+ ions where a promising adsorption performance towards these metal ions with maximum adsorption capacities of 127.3 mg/g and 103 mg/g for Cd 2+ and Pb 2+ ions, respectively, was obtained. The material was also examined for its antifungal properties towards Aspergillus niger and Penicillium notatum , two toxic species of fungi and a good fungicidal property of the composite material was observed. Adual application of Mag@C makes it as a useful material in the process of waste water treatment.
