Vis Spectroscopy

A new fluorescent and colorimetric sensor for Fe3+ ion were synthesized via four-component reaction of acetophenone, dimedone, benzaldehyde and ammonium acetate in the presence of SrFe12O19. The chemosensor shows excellent sensitivity toward Fe3+ ion. The sensing ability of the chemosensor was studied by fluorescent and UV-Vis spectroscopy. The detection limits for Fe3+ were calculated respectively about 8.3 × 10–6 M and 2.3 × 10–6 M for fluorescence and UV-Vis techniques.

Hydrogen Sulphate

This work presents the development of a quinoxaline and rhodamine conjugate system that acts as a colorimetric chemosensor for hydrogen sulfate (HSO4−) ions in methanol media. This sensor has been characterized both theoretically and experimentally. The detection limits for HSO4− are small as 0.71 µM and 3.8 µM for the absorption and emission experiments, respectively. The effectiveness of the probe in recognizing HSO4− both in gel and solid phase is evaluated as well. Thus, this works presents a simple strategy to detect the environmental HSO4− pollutant event at tiny concentrations.
