Synthesis and Characterization of Carbon Nanodots for Detection and Quantification of Ferric (III) Ions

In this research, green electrochemically synthesized Carbon Nanodots (C-Dots) and one-pot microwave synthesized Nitrogen-doped Carbon Nanodots (N-CDs) were studied as chemical sensor for detection of Ferric (Fe3+) ions. C-Dots were synthesized electrochemically through a green chemistry approach us...
