The carbon nanodot particles(CNDs) have focussed attention of scientists because of their versatality of sources for preparation and their multidisciplinary applications. Here ,we obtained CNDs by simple method using banana with 48 % quantum yield. The synthesized carbon dots are characterized by using FTIR, Fluorescence spectroscopy. The metal Fe3+ shows adsorption on carbon nanodots. This property can be used for water remediation and purification purpose. Natural banana fruit was washed, cut into pieces and dried at 105ºc for 24 hours. It was then carbonized at 400ºc for 1.5 hours. Its carbon particles were activated in furnace at 600ºc. FTIR Spectra shows presence of primary amine group, carbonyl group, aromatic conjugated carbon chain. Further, PL Spectra represents n to π* and π to π * transitions, which shows presence of free electron cloud of n & π electrons. XRD shows amorphous nature ,while TEM shows 4 to 6 nm sizes for nanoparticles. Metal adsorption graph of Fe3+ metal shows about 3.35 gm/mole adsorption on carbon nanodots. Carbon nanodots particles can be synthesized easily by wet chemical method by using natural banana. Freundlich and Langmuir isotherms are verified for Fe3+ metal adsorption by carbon nanoparticles. Costwise, synthesis of these nanoparticles is cheaper and can be used to remove metal ion from water.
