Simultaneous adsorption and fluorescent detection of Cr(VI) via lanthanide coordinating polymeric porous microparticles

A cross-linkable phthalonitrile derivative as a precursor to synthesize nitrogen-doped carbon nanodots for Ni ion detection

“…After the N-CD is used for Ni(II) detection, the absorption peaks at 3134 cm À1 and 1595 cm À1 shift to 3141 cm À1 and 1620 cm À1 , respectively, which implies that the carboxyl group is coordinated with Ni 2+ . 49,50 It should be noted that the absorption peak at 1384 cm À1 shifts to 1388 cm À1 , indicating that the nitro group coordinated with Ni 2+ as well. 51 Moreover, Fig.…”

Design of fluorescent polymeric thermometers based on anthrapyrazolone functionalized oligo(ethylene glycol) methacrylates

“…Moreover, polymeric microparticles were reported for simultaneous adsorption and fluorescence detection of hazardous Cr( vi ) ions. 22 Although dyes with anthrapyrazolone moieties have been employed in various applications due to their appealing photophysical properties, their use as fluorescent probes in the biomedical field has been scarcely reported. Thus, the chemical incorporation of the anthrapyrazolone moiety within biocompatible polymers could lead to the synthesis of smart diagnostic materials.…”

Machine Learning Algorithms for Intelligent Decision Recognition and Quantification of Cr(III) in Chromium Speciation

“…For instance, Chen et al prepared a novel nitrogen-doped carbon dot (NCD)-based interpenetrating polymer hydrogel, using nanofibers and chitosan, for the adsorption and fluorescent detection of Cr­(III) . Ran and colleagues reported a novel oligomer-based lanthanide-coordinated polymeric fluorescent probe, which achieved sensitive detection of Cr­(VI) . Yuan et al developed a fluorescent lignin-based hydrogel containing cellulose nanofibers and carbon dots for effective control and detection of Cr­(VI) .…”

“…15 Ran and colleagues reported a novel oligomer-based lanthanide-coordinated polymeric fluorescent probe, which achieved sensitive detection of Cr(VI). 16 Yuan et al developed a fluorescent lignin-based hydrogel containing cellulose nanofibers and carbon dots for effective control and detection of Cr(VI). 17 Although the methods mentioned above each have their advantages, there are still challenges in accurately identifying trivalent chromium in the presence of multiple oxidation states and achieving rapid on-site quantification, requiring further improvements.…”
