Environmental toxicology, 26(5), 489-497 (2010-06-16)
Azo dyes are of environmental concern due to their degradation products, widespread use, and low-removal rate during conventional treatment. Their toxic properties are related to the nature and position of the substituents with respect to the aromatic rings and amino

Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 83(1), 561-569 (2011-10-01)
This study reports the characterization of disperse red 1 acrylate compound by spectral techniques and quantum chemical calculations. The spectroscopic properties were analyzed by FT-IR, UV-vis, (1)H NMR and (13)C NMR techniques. FT-IR spectrum in solid state was recorded in
