“…With this respect, simplicity, high selectivity, low operation costs, and (sometimes) the possibility of naked-eye detection are some advantages of fluorescence sensing techniques over much more sophisticated instrumental techniques. Among the heavy metals, mercury is a highly toxic one since it can readily penetrate through the cell membranes because of its solubility in the lipid bilayer [7,8]. Thus, mercury ions are recognized as a primary source of health problems for living things even at trace levels [9,10].…”

In this study, Fe 3+ ion selective N-(Rhodamine-6G)lactam-N'-acryloyl-ethylenediamine (RH6GAC) monomer was synthesized. Then, p(Acrylamide-co-N-(Rhodamine-6G)lactam-N'-acryloyl-ethylenediamine) (p(AAm-co-RH6GAC)) and p(2-hydroxyethylmethacrylate-co-N-(Rhodamine-6G)lactam-N'-acryloyl-ethylenediamine) (p(HEMA-co-RH6GAC)) colorimetric hydrogels were synthesized by using acrylamide (AAm) and 2-hydroxyethylmethacrylate (HEMA) as primary monomers. FT-IR, SEM, polymerization yield and swelling characterizations were conducted for the resulting hydrogels. Then, these hydrogels were used in selective absorption of Fe 3+ ions from aqueous media. The hydrogels, which could absorb Fe 3+ ions selectively from a mixture of metal ions, were used as column packing material. The solutions containing Fe 2+ and Fe 3+ ions at different concentrations were separated at a rate of 97.7 ± 0.7%.

“…These kinds of compounds generally offer one-step synthesis processes in moderate conditions with high yield. Also, an imine bond, known as carbon-nitrogen double bond (-C=N-), is obtained as a result of Schiff base reaction can readily be used for coordination with metals (7, 21,22). After coordination with metal ions, inhibition of the C=N isomerization cause substantial fluorescent enhancement for such molecules, which is used as obtaining analytical signals (23).…”

A novel anthracene-based dipodal Schiff base ''turn-on'' fluorescent sensor (FS) was designed and synthesized by accessible and straightforward Schiff base reaction of salicylaldehyde and 9,10-bis(aminomethyl)anthracene with high yield. The chemical characterization of fluorescent sensor FS was performed by standard spectroscopic techniques (MALDI-MS, FT-IR, 1 H, and 13 C NMR), and photophysical properties were exanimated by UV-vis and fluorescent spectroscopies. The fluorescent sensor FS can coordinate with Hg 2+ via Schiff base moiety when analytical signal as a "turn on" fluorescent response was obtained via anthracene moiety after coordination. Also, spectrofluorimetric analysis of Hg 2+ was carried out using fluorescent sensor FS in environmental water samples after optimization required experimental conditions such as pH, the time before measurements, and photostability. According to obtained results, the presented fluorescent sensor can be used for selective and sensitive spectrofluorimetric determination of Hg 2+ .
