Abstract: ABSTRACT CARBON NANOMATERIAL-BASED HEAVY METAL DETECTION SYSTEM A method for detecting heavy metals in a sample includes obtaining a plant-derived precursor material that includes dried plant material, subjecting the plant-derived precursor material to hydrothermal treatment to synthesize a carbon nanomaterial exhibiting photoluminescence properties, dispersing the carbon nanomaterial in a liquid medium to form a carbon nanomaterial dispersion, combining the carbon nanomaterial dispersion with a sample to be tested, and observing an optical change in the carbon nanomaterial dispersion. The optical change is indicative of the presence of heavy metal ions in the sample. The carbon nanomaterial may include carbon nanoparticles, carbon-clay composites, or carbon-ethylene diamine composites. The optical change may include a change in photoluminescence intensity, a change in photoluminescence colour, or both, and may be observable with the naked eye without requiring specialised instrumentation.
