“…It could be seen that the fluorescence signal of the PVA-MRBH with Cu 2+ ion remarkably decreased for a few minutes, and leveled off as the time continues. The fluorescence intensity of PVA-MRBH with Cu 2+ reached its minimum value at about 10 min, after which the fluorescence intensity remained almost constant [26,[40][41][42][43][44].…”

“…Earlier we have developed polymeric sensors based on rhodamine in "off-on" mode for the detection of metal cations in aqueous solution [24][25][26]. As part of our continuous work on polymeric chemosensors based on polyving akohol grafting the rhodamine derivative [24], we prepared severally two water-soluble polymers, polyving akohol grafting N-mono-maleic acid amide-N′-rhodamine B hydrazide (PVA-MRBH) and polyving akohol grafting N-mono-succinic acid amide-N′-rhodamine 6G hydrazide (PVA-SR6GH), (Scheme 1).…”

Two rhodamine derivatives, N-mono-maleic acid amide-N'-rhodamine B hydrazide (MRBH) and N-mono-succinic acid amide-N'-rhodamine 6G hydrazide (SR6GH), were synthesized by amidation with maleic anhydride (MAH), succinic anhydride (SAH) and rhodamine B hydrazide, rhodamine 6G hydrazide, which were identified by FTIR, (1)H NMR and elemental analysis. Two water-soluble fluorescent materials (PVA-MRBH and PVA-SR6GH) were prepared via esterification reaction with N-mono-maleic acyl chloride amide-N'-rhodamine B hydrazide (MRBHCl) or N-mono-maleic acyl chloride amide-N'-rhodamine 6G hydrazide (SR6GHCl) and poly(vinyl alcohol) (PVA) in DMSO solution. The sensing behaviors of PVA-MRBH and PVA-SR6GH were explored by recording the fluorescence spectra in completely aqueous solution. Upon the addition of Cu(2+) and Fe(3+) ions to the aqueous solution of PVA-MRBH, visual color change from rose pink to amaranth and orange for Cu(2+) and Fe(3+) ions, respectively, and fluorescence quenching were observed. Titration of Cu(2+), Fe(3+), Cr(3+) or Hg(2+) into the aqueous solution of PVA-SR6GH, although they induced fluorescence enhancement, only Fe(3+) made the color changing from colorless to yellow. Moreover, other metal ions did not induce obvious changes to color and the fluorescence spectra.

“…However, either a Cr 3+ deficiency or an excess amount of Cr 3+ can induce biological disorders in the human body [12,13]. For example, exposure to higher concentrations of Cr 3+ has a negative effect on normal enzymatic activities [14]. The results from several in vitro studies have indicated that high concentrations of Cr 3+ in cells can lead to DNA damage [15].…”

Acrylamide polymer brushes (PAM) were prepared on the surface of Au electrode for Pb 2+ ion sensing via surface-initiated electrochemical-mediated atom transfer radical polymerization (SI-eATRP). The electrode modified with PAM (PAM/Au) was carefully examined by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), polarization modulation infrared reflection-absorption spectroscopy (PM-IRRAS), and scanning electron microscope (SEM). Further, the PAM/Au electrode was successfully used for the determination of Pb 2+ ion by differential pulse anodic stripping voltammetry (DPASV). Under the optimal conditions, the PAM/Au electrode showed a linear correlation for Pb 2+ concentrations in the range of 3.0×10 −3 to 2.0×10 3 μg/L. The limit of detection (S/N = 3.3) was estimated to be 3.7× 10 −4 μg/L. Finally, polymer brush electrodes were applied to analyze Pb 2+ ion in an effluent. The results of the experiment indicated that PAM/Au electrode has good accuracy and potential application in practical sample analysis. In a word, the work of this paper established a useful way for the synthesis and application of polymer brush.
