Abstract

In this work, we report a simple method to synthesized Carbon nanoparticles (CNP) from sucrose by using sulphuric acid at room temperature. The CNP is characterized with UV-visible, FT-IR, powder X-ray diffraction and transmission electron microscopy (TEM). The particle sizes of the CNP are in the range 10 nm to 30 nm with mean size of 19.82 nm. The CNP show bright blue fluorescence, sensitive to pH and strong stability towards NaCl concentration. The fluorescence of the CNP is found to be independent of excitation wavelength. Moreover, we have demonstrated the capability of CNP for selective Fe3+ ions detection in aqueous medium, tap water to minimum detection limit of 10 nM. The linear range dependent of Fe3+ concentration is 1 μM to 25 μM. Therefore, this fluorescent CNP may used for detection Fe3+ ions in water system and biological samples.
