Fabrication characterization and potential applications of carbon nanoparticles in the detection of heavy metal ions in aqueous media

Polyaromatic hydrocarbon inner-structured carbon nanodots for interfacial enhancement of carbon fiber composite

“…49,50 The XRD main peaks of previously reported CNDs usually vary from 17 to 26 , indicating the different distances between the adjacent carbon atomic planes of the CNDs. 15,[51][52][53][54] These XRD results do not indicate a graphite or graphene structure carbon atomic plane directly, because of similar results in polymer research. The 13 C NMR, FT Raman spectroscopy, and FT-IR spectroscopy results conrm that the MGSH CNDs in this work have PAH carbon atomic planes.…”

A novel method for the preparation of solvent-free, microwave-assisted and nitrogen-doped carbon dots as fluorescent probes for chromium(vi) detection and bioimaging

“…[16][17][18][19][20][21] Several approaches have been developed for the detection of heavy metal ions based on CDs. [22][23][24][25][26][27][28] For example, Liu et al 23 prepared CDs through the hydrothermal treatment of grass to detect cupric ion, and the detection concentration limit could be as low as 1 nM. Dang et al 25 synthesized highly uorescent N and S co-doped CDs using high-temperature pyrolysis; these CDs were very effective for the detection of silver ions.…”

Comparison between Modified and Unmodified Carbon Paste Electrodes for Hexavalent Chromium Determination

“…Extreme toxicity of heavy metals and their adverse effects on the environment has engendered enormous necessity to develop selective, low cost, cheap and fast methods to detect them . Among these heavy metals we find chromium, on one hand, trivalent chromium is an essential element for human health, and its insufficiency increases the risk factors associated with diabetes and cardiovascular diseases .…”
