Dicarbohydrazide based chemosensors for copper and cyanide ions via a displacement approach

27-May-2018 | Neetu Yadav; Ashok Kumar Singh, New Journal of Chemistry, 2018

Ligands attached to pyridine dicarbohydrazide were synthesized and characterized by NMR, FT-IR, elemental analysis, UV-visible spectroscopy, mass spectrophotometry, emission spectra and single crystal X-ray diffraction. These ligands were found to recognize copper ions over other metal ions and ...

The study of the influence of Mg(II) and Ca(II) ions on caffeic acid autoxidation in weakly alkaline aqueous solution using MCR-ALS analysis of spectrophotometric data

25-May-2018 | Slavoljub C. Živanović; Aleksandar M. Veselinović; Žarko J. Mitić; Goran M. Nikolić, New Journal of Chemistry, 2018

UV-Visible spectrophotometry was used to study the influence of Mg(ii) and Ca(ii) ions on caffeic acid (CA) autoxidation in weakly alkaline aqueous solution. While the autoxidation rate was very slow in the absence of metal ions, both Mg(ii) and Ca(ii) ions greatly enhanced the autoxidation rate. ...
